Faith, Science & Evidence

Why We Put This Together

Christian faith has nothing to fear from honest questions, and our students deserve to see that for themselves. As One Christian Academy grows into middle and high school, our students are beginning to examine the beliefs they received from their parents, church, and school. That is not a crisis. It is a normal and healthy stage of growing up, and it is the moment when a faith that is merely inherited can become a faith that is truly owned.

This guide gathers resources from Christian scholarship, secular academic research, medicine, philosophy, and scientific institutions. Some sources defend Christian belief. Others present skeptical explanations. Some reach no conclusion about God at all. We include all of them on purpose, because a student who has heard the strongest objections from a trusted teacher is far better prepared than one who first hears them in a university lecture hall.

Who this guide is for

This guide is written for OCA parents, teachers, and our wider church community, beginning in the middle school years. Students bring their questions home and to church, not only to school, so we want every adult in their lives to be ready to answer with confidence, gentleness, and the right direction.

Students themselves meet this material in stages, at the level that fits their age:

• Grade 6, Roots: students know God and memorize key Scripture verses. Hard questions are not the focus yet.
• Grades 7-8, Building: a gentle introduction to evidence, always pointing back to Scripture.
• Grades 9-12, Standing firm: honest discussion of hard questions and opposing views, so that students are prepared before they leave for college.

Adults, however, should be ready at every stage, because a child may hear a challenge from a friend, a video, or the internet at any age.

The guide is organized around the questions students actually ask:

1. How should we think about evidence in the first place?
2. Is there good reason to believe God exists?
3. Can we trust the Bible, given its many authors, its long history of copying, and its miracle accounts?
4. Did Jesus really exist?
5. Did Jesus rise from the dead?
6. Can a serious scientist also be a serious Christian?

It closes with guidance for teachers, short answers to common student questions, guidance for families, and an appendix on near-death experiences and consciousness for older students.

A Note About Evidence

Nothing in this guide is presented as scientific “proof” of God, the Bible, or the resurrection. History and science work with probabilities and best explanations, not mathematical certainty. The honest claim is more modest and, we believe, more persuasive: Christian faith does not stand on these findings, but it is not contradicted by them, and it can be held with full intellectual integrity.

Throughout the guide, we ask students the same six questions:

• What does the evidence actually show?
• What are the possible explanations?
• What assumptions is each explanation making?
• What are the strengths and weaknesses of each explanation?
• What evidence would challenge my own position?
• Am I willing to follow the evidence wherever it leads?

These questions reflect OCA’s pillar of being Deeply Challenged while remaining Deeply Rooted in Christ.

Faith First: Where This Guide Stands

Our faith does not rest on science, history, or human reasoning. It rests on God himself, who has made himself known in creation, in Scripture, and above all in Jesus Christ. Nothing in this guide is meant to prove God, to argue anyone into belief, or to show that we are right and others are wrong.

What we believe at OCA: we believe in the one true God. We believe the Bible is God’s Word. And we believe that salvation comes only through Jesus Christ (John 14:6; Acts 4:12). This guide is written from within that faith, not as a search for it. Within that faith, we encourage students to bring their questions and examine them honestly, so that when they hear different ideas from others, they can stand firm in a faith that is truly their own.

God is greater than our findings

God is beyond our logic, and we cannot limit his power, his work, or his love to what our instruments can measure or our minds can fully explain.

“For my thoughts are not your thoughts, neither are your ways my ways,” declares the LORD. “As the heavens are higher than the earth, so are my ways higher than your ways and my thoughts than your thoughts.” (Isaiah 55:8-9)

Oh, the depth of the riches of the wisdom and knowledge of God! How unsearchable his judgments, and his paths beyond tracing out! (Romans 11:33)

Science studies the physical world God made. It is a good and God-honoring work, but it is limited by its nature to what is physical, measurable, and repeatable. Human findings change as knowledge grows. God does not change. A faith built on the latest discovery would rise and fall with the next one. A faith built on Christ stands firm.

Saving faith is a gift of God’s grace through the Holy Spirit, not a conclusion we reach on our own (Ephesians 2:8-9; 1 Corinthians 2:4-5). “By faith we understand that the universe was formed at God’s command” (Hebrews 11:3).

Then why study the evidence?

Because God gave us minds and calls us to love him with them (Matthew 22:37). Christians have long described this as faith seeking understanding: we believe, and because we believe, we want to understand more deeply. The evidence in this guide serves that purpose.

One picture helps: Christ is the foundation (1 Corinthians 3:11). The evidence is not the foundation. It is more like a survey of the ground, which helps students see that the ground they are building on is solid and trustworthy.

Scripture invites honest questions

The Bible does not ask us to stop thinking. It shows God’s people asking, examining, and remembering.

• Be ready to give a reason: “Always be prepared to give an answer to everyone who asks you to give the reason for the hope that you have. But do this with gentleness and respect” (1 Peter 3:15).
• Examine carefully: the Bereans “examined the Scriptures every day to see if what Paul said was true,” and Luke calls them noble for it (Acts 17:11).
• Investigate the record: Luke “carefully investigated everything from the beginning” so that his reader would “know the certainty of the things you have been taught” (Luke 1:1-4).
• Jesus meets doubt with love: when Thomas doubted, Jesus did not reject him. He came to him and invited him to see. Then he added, “Blessed are those who have not seen and yet have believed” (John 20:24-29).
• Creation points to its Maker: “The heavens declare the glory of God” (Psalm 19:1; see also Romans 1:20).

Faith grows in more than the mind

Students come to know God not only by studying evidence, but by praying, reading Scripture, worshiping, serving, and belonging to a community of believers. Arguments can clear the way, but it is God who draws people to himself (John 6:44). As teachers and parents, our role is to plant and water. God gives the growth (1 Corinthians 3:6-7).

Scripture quotations are from the New International Version (NIV).

Part I. How to Think About Evidence

Before students evaluate any argument about faith, they need tools for evaluating arguments at all. Most disagreements about God and the Bible are not disagreements about the facts. They are disagreements about how to interpret the facts, and about the assumptions people bring to them.

Five words every student should know

What history and science can and cannot do

Science investigates the natural world through observation, measurement, and repeatable testing. It is extraordinarily good at telling us how the physical world works. It is not designed to answer questions such as why anything exists, whether life has a purpose, or what is morally good. Those are philosophical and theological questions, though science can inform them.

History cannot repeat past events in a laboratory. Historians instead weigh documents, artifacts, and testimony to determine what most probably happened. This is how we know about Julius Caesar or Alexander the Great, and it is the same method scholars apply to Jesus.

The key lesson: a person’s starting assumptions often decide their conclusion before the evidence is examined. If someone assumes miracles cannot happen, no historical evidence for a miracle will ever persuade them. If someone assumes God exists, a miracle becomes possible, though it still needs evidence. Students should learn to notice these assumptions, including their own.

Respecting experts without worshipping them

Students should respect expertise. They should also know that experts disagree, that experts have worldviews too, and that a confident tone is not the same as a strong argument. A good habit: whenever students read a strong claim, ask “What would someone on the other side say?”

Part II. Is There Good Reason to Believe God Exists?

The existence of God cannot be proven in a laboratory, but several lines of evidence point beyond the physical world, and many serious thinkers find them persuasive. Each argument below has a serious response from skeptics, and students should hear both.

Keep this in perspective: Christians do not believe in God because of these arguments. God has made himself known through creation, through Scripture, and fully in Jesus Christ (Hebrews 1:1-3). The arguments below cannot contain God or measure him. They help students see that belief in God is not opposed to careful thinking, and that the world we observe is consistent with what Scripture teaches.

1. Why is there something rather than nothing? (The cosmological argument)

Modern cosmology describes the universe developing from an extremely hot, dense early state, the Big Bang (NASA Science: The Big Bang; NASA Science: Universe Overview). Science can trace the physical history of the universe back toward that state. It cannot, by itself, answer the deeper question of why there is a universe at all.

The cosmological argument reasons that everything that begins to exist, or that depends on something else for its existence, needs an explanation outside itself. The ultimate explanation, it argues, is a necessary, uncaused being, which is what Christians mean by God.

• Skeptical responses: the universe may simply be a “brute fact” with no explanation; our intuitions about causes may not apply to the universe as a whole; or physics may eventually describe a universe without a beginning.
• Read both sides: Stanford Encyclopedia of Philosophy: Cosmological Argument

2. Why does the universe allow life? (The fine-tuning argument)

Several physical constants appear to fall within narrow ranges that permit stars, chemistry, and life. Scholars respond in four main ways: deny that fine-tuning is a real puzzle, infer a designer, expect new physics to explain it, or propose a multiverse in which our universe is one of many (Stanford Encyclopedia of Philosophy: Philosophy of Cosmology; Teleological Arguments for God’s Existence).

We should not tell students “fine-tuning proves God.” We can ask: Which explanation is simplest, best supported, and least ad hoc?

3. Where does morality come from? (The moral argument)

Nearly everyone believes some things are truly wrong, not merely unpopular, such as torturing a child for fun. The moral argument asks what could make moral obligations objectively binding. Christians answer that moral law reflects the character of a good God. Skeptics answer that morality can be grounded in human nature, reason, or social cooperation without God (Stanford Encyclopedia of Philosophy: Moral Arguments for the Existence of God). C. S. Lewis’s Mere Christianity, Book One, is an accessible version for older students.

4. Why is there a mind at all? (Consciousness)

Science has mapped many correlations between brain activity and experience, yet there is still no agreed theory explaining why subjective experience exists. Philosophers call this the “hard problem” of consciousness (Stanford Encyclopedia of Philosophy: Consciousness). This does not prove that the mind is independent of the brain. It does mean that the claim “science has fully explained the mind” goes beyond the evidence. The Appendix develops this further.

5. How did life begin? (Origin of life)

Students often confuse two separate questions. Evolution addresses how populations of living things change over time. The origin of life asks how the first living systems arose from nonliving chemistry. The second question remains unsolved and is an active field of research, which NASA funds through its Astrobiology Program (NASA Astrobiology: Program Overview; NASA Astrobiology: For Researchers).

A caution for teachers: avoid a “God of the gaps” argument, in which God is invoked only where science has no answer yet. If science later fills the gap, a faith built on it is shaken. Christians historically have seen God as the author of the whole natural order, including the parts science explains well.

6. The strongest objection: the problem of evil and suffering

If God is all-good and all-powerful, why is there so much suffering? This is the most common reason people give for rejecting God, and students deserve to hear it treated seriously rather than brushed aside. Christian responses include the value of genuine free will, the possibility that God has reasons we cannot see, and, most centrally, the claim that God has entered human suffering himself in Jesus’ crucifixion and promises to end it in the resurrection (Stanford Encyclopedia of Philosophy: The Problem of Evil).

Accessible reading for students and families

Part III. Can We Trust the Bible?

The Bible has many human authors, a long history of copying, and accounts of miracles, and students are right to ask about all three. The evidence shows that the Bible we read today faithfully preserves what was originally written, and that its historical setting is repeatedly confirmed by archaeology. Whether it is the Word of God is a question of faith, but it is a faith supported by evidence rather than opposed to it.

1. “The Bible has so many different voices”

This is true, and it is a strength rather than a weakness. The Protestant Bible contains 66 books written by roughly 40 authors over more than 1,000 years, in Hebrew, Aramaic, and Greek. Its authors include kings, shepherds, priests, prophets, a tax collector, a physician, and fishermen.

• Many genres: the Bible is a library, not a single book. It contains history, law, poetry, proverbs, prophecy, biographies (the Gospels), letters, and apocalyptic visions. Each genre must be read on its own terms. When Isaiah says “the trees of the field will clap their hands” (Isaiah 55:12), no one is meant to picture literal trees with hands.
• Many witnesses: the four Gospels tell the story of Jesus from four perspectives, with differences in detail and emphasis. Historians generally treat this as a mark of independent testimony. Four perfectly identical accounts would suggest copying or collusion.
• One story: despite this diversity, the Bible tells a coherent story of creation, fall, redemption, and restoration.
• Christian view of inspiration: Christians believe the Bible has dual authorship. Human authors wrote with their own personalities, vocabulary, and historical context, while God guided the result (2 Timothy 3:16; 2 Peter 1:20-21). Inspiration does not mean dictation.

2. “The Bible has been edited and changed over time”

This concern usually combines two different questions, which should be separated.

Question A: Were biblical books compiled or edited before they were finished? Some were, and the Bible itself says so. Proverbs includes collections from Solomon, “the men of Hezekiah,” Agur, and Lemuel (Proverbs 25:1; 30:1; 31:1). Luke says he researched earlier sources (Luke 1:1-4). Christians affirm that God’s guidance extended through this whole process to the finished text.

Question B: Has the text been corrupted since it was finished? This is where the evidence is strongest.

• New Testament manuscripts: roughly 5,800 to 6,000 handwritten Greek manuscripts have been catalogued, plus thousands more in early translations such as Latin, Syriac, and Coptic. Textual scholar Daniel Wallace notes that the official count stands near 6,000, with important caveats about how fragments are counted (danielbwallace.com; Center for the Study of New Testament Manuscripts). No other ancient work comes close. Most classical works survive in a few dozen to a few hundred copies, often written many centuries after the original.
• Early copies: substantial papyri of the Gospels and Paul’s letters date to the 200s AD, and complete New Testaments survive from the 300s (Codex Sinaiticus and Codex Vaticanus).
• What about the variants? Because there are so many copies, there are many differences among them, estimated in the hundreds of thousands. The vast majority are spelling, word order, or obvious copying slips that do not affect meaning. Comparing thousands of manuscripts lets scholars identify the original wording with high confidence.
• Be honest about the exceptions: a few passages are widely judged to be later additions, most notably the longer ending of Mark (Mark 16:9-20) and the woman caught in adultery (John 7:53-8:11). Modern Bibles openly mark these with brackets or footnotes. Showing students these footnotes builds trust. No core Christian teaching depends on these passages. Even skeptical textual critic Bart Ehrman, in an interview included in the paperback edition of Misquoting Jesus (2005), acknowledged that essential Christian beliefs are not affected by textual variants.
• Old Testament and the Dead Sea Scrolls: before 1947, the oldest complete Hebrew Old Testament manuscripts dated to around AD 900-1000. The Dead Sea Scrolls, discovered near Qumran beginning in 1947, include copies of every Old Testament book except Esther, some more than 1,000 years older. The Great Isaiah Scroll is strikingly close to the later text, while other scrolls show some variant forms, which scholars openly study. Students can view the scrolls themselves at the Leon Levy Dead Sea Scrolls Digital Library.

3. “How do we know which books belong in the Bible?”

The early church did not invent the canon by vote. It recognized books already widely used as authoritative, especially those connected to the apostles. The four Gospels and Paul’s letters were broadly accepted by the late 100s AD, and Athanasius listed exactly the 27 books of today’s New Testament in AD 367. Students should also know that Catholic and Orthodox Bibles include additional Old Testament books (the Apocrypha or Deuterocanonical books), and why Protestants do not.

4. What archaeology confirms

Archaeology repeatedly confirms the people, places, and customs the Bible describes.

Be honest about the limits. Archaeology confirms historical settings, not theological claims. Some biblical events, such as the lives of the patriarchs and the Exodus, have little direct archaeological evidence, and scholars debate them. Absence of evidence is not proof that an event did not happen, especially for ancient nomadic peoples, but students should hear that these debates exist.

5. “The Bible includes unrealistic events”

This objection usually rests on an assumption: that miracles are impossible. That assumption is philosophical, not scientific. Science describes how nature normally behaves. It cannot rule out that the Creator of nature might act within it.

Three questions help students:

1. What genre is this passage? Poetry and apocalyptic visions use symbolic language. Reading genre correctly resolves many apparent problems.
2. If God exists, are miracles possible? If the answer is yes, the question becomes historical: is there good evidence that this particular event happened?
3. Which miracle matters most? The whole Christian faith rests on one event, the resurrection of Jesus (1 Corinthians 15:14-17). Parts IV and V focus there.

For teachers who want to go deeper, Craig Keener’s two-volume Miracles: The Credibility of the New Testament Accounts examines both the philosophical debate and documented modern miracle claims.

A note on Genesis and science: OCA firmly believes that God is the Creator of all things (Genesis 1:1; Hebrews 11:3). Bible-believing Christians hold different views on how Genesis 1-11 relates to scientific accounts of the age of the earth and the development of life, including young-earth creation, old-earth creation, and evolutionary creation. OCA does not require students to adopt one of these views. Teachers should present the main Christian views fairly, emphasize what Scripture clearly teaches (God created everything, people are made in his image, and creation is good), and encourage students to examine these questions with their families and churches.

Part IV. Did Jesus Really Exist?

Yes. Virtually all historians who study the ancient world, Christian and non-Christian alike, agree that Jesus of Nazareth was a real person. The claim that he never existed (sometimes called “mythicism”) is a fringe position rejected by mainstream scholarship.

Agnostic New Testament scholar Bart Ehrman, one of the best-known critics of traditional Christianity, wrote an entire book, Did Jesus Exist? (2012), defending Jesus’ historical existence against mythicists. This is a useful example for students: a scholar who does not share our faith nonetheless affirms the historical foundation.

What historians widely agree on

• Jesus was a Jewish teacher from Galilee.
• He was baptized by John the Baptist.
• He gathered disciples and was known as a teacher and healer.
• He was crucified in Jerusalem under the Roman prefect Pontius Pilate, around AD 30-33.

Evidence from outside the Bible

These writers had no reason to promote Christianity. Tacitus called it a “deadly superstition.” Their testimony is valuable precisely because it comes from outsiders.

The earliest Christian sources

The letters of Paul were written in the AD 50s, only about 20-25 years after Jesus’ death, and are the earliest Christian writings we have. Paul mentions meeting Peter and “James the Lord’s brother” in person (Galatians 1:18-19). Most scholars date the Gospels to roughly AD 65-95, within the lifetime of eyewitnesses. By the standards of ancient history, this is remarkably close to the events. The earliest surviving biographies of Alexander the Great were written about 400 years after his death.

A good teaching question

If nearly all historians agree that Jesus existed and was crucified, the more interesting question is not whether he lived but who he was. That leads directly to Part V.

Part V. Did Jesus Rise from the Dead?

The resurrection is the center of Christianity. Paul himself wrote that if Christ has not been raised, Christian faith is futile (1 Corinthians 15:14-17). The historical question is: what best explains the earliest Christian belief that Jesus rose from the dead? Christians argue that the actual resurrection explains the evidence better than any alternative.

1. The earliest testimony: 1 Corinthians 15:3-7

Around AD 53-55, Paul wrote down a short summary of the faith that he says he had “received” and “passed on”: Christ died for our sins, was buried, was raised on the third day, and appeared to Peter, to the Twelve, to more than 500 people at once, to James, and to all the apostles. Many scholars, including skeptical ones, believe Paul received this formula within a few years of the crucifixion. That makes it one of the earliest pieces of Christian testimony, far too early to be a late legend.

2. Facts most historians accept

Scholar Gary Habermas surveyed academic writing on the resurrection and identified a set of “minimal facts” accepted by most scholars across the spectrum, including skeptics:

1. Jesus died by crucifixion.
2. Soon afterward, his disciples sincerely believed he had appeared to them alive.
3. Paul, a persecutor of the church, became a Christian after what he believed was an appearance of the risen Jesus.
4. James, Jesus’ skeptical brother, also became a believer and a church leader.
5. Jesus’ tomb was found empty. (A majority of scholars accept this, though fewer than accept points 1-4.)

Other features historians find significant:

• Women as first witnesses: in first-century culture, women’s testimony carried less legal weight. Inventing a story would not have made women the first witnesses. Historians call this the “criterion of embarrassment.”
• An unexpected belief: Jews expected a resurrection of all the righteous at the end of history, not one man rising in the middle of it. Nor did they expect a crucified Messiah. The disciples’ claim did not fit their own expectations.
• Transformed lives: the disciples went from hiding in fear to proclaiming the resurrection publicly, at great personal cost.

3. Weighing the explanations

Ask students: Which explanation accounts for the most evidence with the fewest extra assumptions? And what assumption about miracles does each explanation start with?

4. Scholars to read on both sides

The question is not simply “Which scholar do I agree with?” It is “Which argument is better supported, and why?“

Beyond the historical question

History can show that the resurrection is the best explanation of the evidence. It cannot make anyone trust the risen Christ. When Thomas saw Jesus, he did not say “The evidence is convincing.” He said, “My Lord and my God!” (John 20:28). The goal of this section is not to win a debate, but to help students see that the hope of the gospel rests on a real event, and then to invite them to know the risen Lord personally.

Part VI. Can a Serious Scientist Be a Serious Christian?

Yes. Many of the founders of modern science were devout Christians, and many leading scientists today still are. Their faith does not prove Christianity true, since there are also brilliant scientists who are atheists. The point is narrower and important: science and Christian faith are not inherently at war.

Scientists today

Francis Collins, MD, PhD, is a physician-geneticist who led the Human Genome Project and later served as Director of the National Institutes of Health (NIH Almanac: Francis S. Collins). He describes his journey from atheism to Christian faith in The Language of God (2006) and founded BioLogos, an organization exploring science and faith.

Jennifer Wiseman, PhD, is a senior astrophysicist at NASA’s Goddard Space Flight Center and Senior Project Scientist for the Hubble Space Telescope, with a PhD in astronomy from Harvard (NASA: Dr. Jennifer J. Wiseman). She speaks and writes openly about faith, meaning, and science.

Scientists in history

A good discussion question: Many early scientists said they studied nature because they believed a rational God made an orderly world. Why might that belief encourage science?

Part VII. Guidance for Teachers

When a student raises a hard question, the best first response is usually: “That is a very good question. Let’s investigate it together.” How we respond teaches as much as what we say.

Using this guide by grade level

Roots before questions. Students should know God and stand firm in his Word before they wrestle with challenges to their faith. OCA’s approach moves in stages, so that by the time students leave for college, they have been trained to meet any question with the right direction.

Responding to a student’s doubt

• Welcome the question. A student who asks is still engaging. A student who is shamed for asking often simply stops asking out loud.
• Find out what kind of doubt it is. Some doubts are intellectual (“How do we know the Gospels are reliable?”). Others are emotional or personal (“Why did God let my grandmother die?”). Personal doubts call for compassion and presence before arguments.
• Do not overstate the evidence. Claiming that something is “proven” when it is not damages trust when students later learn otherwise. Honest confidence is more persuasive than exaggeration.
• It is fine to say “I don’t know.” Then model how to find out.
• Present opposing views at their strongest. If students only hear weak versions of objections, they will be unprepared when they meet the real ones.
• Involve the community. When a student seems deeply troubled, involve the school’s leadership, chaplain or pastor, and the student’s family according to OCA policy.

Keep the foundation in view. Evidence can answer a question, but only God can change a heart. Alongside discussion, pray for and with your students, open the Scriptures together, and point them to Christ himself. Remind students that it is fine not to have every answer, because our confidence rests in who God is, not in how much we can explain.

Classroom activities (grades 7-12)

1. Steel-man exercise: students state the strongest version of a view they disagree with, until a classmate who holds that view says “Yes, that’s what I mean.”
2. Evidence sort: give students statements about the resurrection or the Bible and have them sort each into evidence, interpretation, or assumption.
3. Source check: students evaluate a website or video on one of these topics. Who wrote it? What are their qualifications? Do they cite sources? Do they present the other side?
4. Assigned-side debate (grades 9-12): students argue a position assigned to them, not one they chose, then reflect on what they learned.
5. Manuscript lab: show students a modern Bible’s footnotes on Mark 16 or John 8, then explore images from the Dead Sea Scrolls digital library.

Discussion questions

• Why do you think the Gospel writers included details that might embarrass the disciples?
• If the Gospels agreed word for word, would that make them more or less believable? Why?
• What would it take to change your mind about God? What would it take to change a skeptic’s mind?
• Can science answer every important question? Which questions can it not answer?
• What is the difference between “we have not found evidence yet” and “there is evidence against”?
• Why do intelligent, sincere people reach different conclusions about God?

Common Student Questions

These are starting points for teachers, parents, and church leaders, not scripts to end a conversation. Listen first, ask what prompted the question, and then use these as a beginning. With younger children, a short, warm answer and a related memory verse are often enough.

Part VIII. Guidance for Parents and Families

If your child is questioning what they have been taught about God, take heart: this is a normal part of growing into adulthood, and it is often the path to a stronger, more personal faith. Your calm, open response matters more than having every answer.

What your child is learning, and when

Prepare before the questions come

Your child may not be asking hard questions yet, and that is perfectly fine. The best time to build a strong foundation is before the storms come (Matthew 7:24-25). Pray with your child, read the Bible together, and help them memorize Scripture now, so that when they hear different ideas later, the truth is already in their hearts.

“Start children off on the way they should go, and even when they are old they will not turn from it.” (Proverbs 22:6)

What helps

• Stay curious, not alarmed. Ask “What made you start thinking about that?” before offering answers.
• Listen fully. Teenagers are more likely to keep talking when they feel heard rather than corrected.
• Share your own journey. Tell them about questions you have wrestled with and how you worked through them.
• Explore together. Read a chapter from one of the books in this guide together, or watch a debate between a Christian and a skeptic and talk about it afterward.
• Live the faith you hope they will keep. Young people are deeply influenced by whether the faith they see at home is honest, joyful, and real.
• Stay connected with the school. OCA teachers and leadership want to partner with you. Please reach out if you would like to talk.

What tends to hurt

• Treating questions as rebellion or disrespect
• Saying “You just have to have faith” as a way to end the conversation
• Panicking, which can signal that the faith cannot withstand questions
• Pretending to know answers you do not

Research Toolkit and Source Notes

How high school students can investigate for themselves

Encourage students to search from more than one perspective. Instead of only searching “evidence Christianity is true,” also search:

• arguments against the resurrection
• historical explanations for resurrection belief
• Jewish views of Jesus and the Messiah
• near-death experiences skeptical explanations
• consciousness and the brain
• fine-tuning arguments for and against God
• origin of life research
• textual criticism of the New Testament

Reliable research databases

About the sources in this guide

The research links in this guide were checked in October 2026. Including a source does not mean OCA endorses all of its conclusions. We include skeptical and secular sources on purpose, so that adults and older students understand the challenges they may hear and can respond thoughtfully, always from the foundation of God’s Word. If you find a broken link or have a question about a source, please contact the school office.

A Final Thought for OCA

We want our students to graduate as young people who can say:

• “I am not afraid of questions.”
• “I can listen to people who disagree with me.”
• “I can examine evidence honestly.”
• “I know the difference between evidence and interpretation.”
• “I can recognize what I know and what I do not know.”
• “My faith does not require me to stop thinking.”

And ultimately:

“I can love the Lord my God with all my heart, all my soul, and all my mind” (Matthew 22:37).

We study the evidence with humility and gratitude, knowing that God is always greater than our understanding. Our findings will grow and change. He does not. Our students’ faith does not stand on what science or history can prove, but on Jesus Christ, the same yesterday and today and forever (Hebrews 13:8).

That is what it means to be Deeply Known, Deeply Challenged, and Deeply Rooted in Christ, and it is the kind of Christian intellectual formation we hope to cultivate at One Christian Academy.
