About This Study Guide
Timothy Keller's The Reason for God is both a dismantling of the most common objections to Christian faith and a positive case for why belief in the God of the Bible is not only intellectually respectable but compelling. Keller, founding pastor of Redeemer Presbyterian Church in Manhattan, spent years listening to the doubts of educated, thoughtful skeptics in one of the most secular cities in America. The result is a book structured in two halves: the first six chapters engage the strongest objections to Christianity head-on — suffering, exclusivity, hell, the reliability of the Bible, the problem of a "repressive" church, and the apparent incompatibility of science and faith. The second half then builds a constructive case for the Christian faith, arguing that the human hunger for meaning, morality, justice, and beauty all point toward a God who is really there.
This study guide is designed for small groups or individual readers who want to go slowly and carefully through Keller's arguments. Each week, read the assigned chapter before your group meets or your personal study time. After reading, pause to journal your honest reactions — what challenged you, what surprised you, what you found yourself resisting. Then bring those responses into the discussion questions below. You don't need a theology degree to engage this material; Keller writes for intelligent non-specialists, and the questions here are designed to help you think more clearly and honestly, not to produce "correct" Sunday-school answers.
Whether you are a committed Christian wanting to think more carefully about your faith, a skeptic genuinely weighing the claims of Christianity, or someone in between, this guide is for you. By the end, you will have wrestled seriously with the hardest objections to faith, engaged the philosophical foundations beneath your own worldview, and considered the person and work of Jesus Christ as the center of any coherent answer to the deepest human questions. Expect your assumptions — whatever they are — to be challenged. That is precisely what Keller intends.

Week 1: Introduction — The Leap of Doubt
Free sampleRead the Introduction of The Reason for God by Timothy Keller.
1.Keller describes the congregation at Redeemer Presbyterian in Manhattan as filled with both fervent believers and committed skeptics who sat side by side. What does that picture suggest about the kind of conversation he is trying to create in this book — and what kind of conversation are you hoping to have in this study?
2.Keller argues that a "leap of doubt" is just as much a faith commitment as a "leap of faith" — that to doubt Christianity requires trusting a set of assumptions that are themselves unproven. Do you find that argument initially compelling or annoying? Why?
3.He notes that the New Atheist books (Dawkins, Hitchens, Harris, Dennett) were dominating bestseller lists when he wrote this book. Do you think the cultural moment has shifted since 2008, or do the same objections still carry the same emotional weight in your circles?
4.Keller says that the doubts of skeptics and the doubts of believers are, in many ways, mirror images of each other — secular people have "faith" commitments they rarely examine, and Christians have doubts they rarely voice. Which side of that mirror are you on, and how honestly have you examined your own unexamined assumptions?
5.The book is divided into two parts: dismantling objections, then building a positive case. Why do you think Keller chose to lead with the objections rather than the positive arguments? What does that rhetorical choice communicate about his respect (or lack of it) for his readers?
6.What is the one objection to Christianity — or the one unanswered question about faith — that you most hope this book will address? Write it down before you go further, so you can return to it at the end.
Week 2: Chapter 1 — There Can't Be Just One True Religion
Read Chapter 1 of The Reason for God by Timothy Keller.
1.Keller opens with the common assertion that "all religions are basically the same" or that "no one religion can be right and the rest wrong." What is the emotional appeal of that view? Where have you heard it most often — from friends, culture, social media?
Week 3: Chapter 2 — How Could a Good God Allow Suffering?
Read Chapter 2 of The Reason for God by Timothy Keller.
1.Keller describes sitting with people in his congregation who have experienced devastating loss and who ask, "How could a good God allow this?" Before you engage the arguments, sit with that question personally: Have you ever asked it yourself, or has someone close to you asked it? What did it feel like?
Week 4: Chapter 3 — Christianity Is a Straightjacket
Read Chapter 3 of The Reason for God by Timothy Keller.
1.Keller quotes the common complaint that Christianity's moral rules restrict personal freedom and individual self-expression. How prevalent is this objection in the culture around you? Where do you most often encounter it?
Week 5: Chapter 4 — The Church Is Responsible for So Much Injustice
Read Chapter 4 of The Reason for God by Timothy Keller.
1.Keller acknowledges the genuine historical evils done in the name of Christianity without flinching. How did you respond to his willingness to admit the church's failures? Does intellectual honesty about Christian history strengthen or weaken his overall case, in your view?
Week 6: Chapter 5 — How Can a Loving God Send People to Hell?
Read Chapter 5 of The Reason for God by Timothy Keller.
1.What is your instinctive reaction to the traditional Christian doctrine of hell? Where did that reaction come from — upbringing, culture, personal experience, theology?
Week 7: Chapter 6 — Science Has Disproved Christianity
Read Chapter 6 of The Reason for God by Timothy Keller.
1.How prevalent is the assumption that "science has disproved God" in your workplace, school, or social circles? What specific scientific findings or arguments are usually cited to support it?
Week 8: Chapter 7 — You Can't Take the Bible Literally
Read Chapter 7 of The Reason for God by Timothy Keller.
1.What is your own history with the Bible — have you read it extensively, occasionally, or rarely? What is your default assumption about its reliability going into this chapter?
Week 9: Interlude — The Clues of God
Read the Interlude of The Reason for God by Timothy Keller.
1.Keller describes the Interlude as a transition from "clearing away objections" to "building a positive case." Why might this two-step structure be more persuasive than simply leading with arguments for God's existence? What is he assuming about his reader's state of mind?
Week 10: Chapter 8 — The Clue of Creation
Read Chapter 8 of The Reason for God by Timothy Keller.
1.Keller opens Part Two by arguing that the skeptic also requires faith — faith that the universe has no personal origin. He says that theism and atheism are both metaphysical commitments that go beyond what science can demonstrate. Do you think that is a fair characterization of atheism?
Week 11: Chapter 9 — The Knowledge of God
Read Chapter 9 of The Reason for God by Timothy Keller.
1.Keller opens by observing that virtually all people, in all cultures and times, have shared certain core moral intuitions: that gratuitous cruelty is wrong, that justice matters, that human dignity deserves respect. Where do you think these intuitions come from? What is the strongest naturalistic explanation you have encountered?
Week 12: Chapter 10 — The Problem of Sin
Read Chapter 10 of The Reason for God by Timothy Keller.
1.How do you typically hear the word "sin" used in culture — in churches, in media, in everyday conversation? What associations does it carry? How does Keller's definition of sin differ from the typical popular understanding?
Week 13: Chapter 11 — Religion and the Gospel
Read Chapter 11 of The Reason for God by Timothy Keller.
1.Keller draws a sharp contrast between "religion" (I obey, therefore God accepts me) and "gospel" (God accepts me in Christ, therefore I obey). Before reading this chapter, how would you have described the relationship between behavior and God's acceptance? Has Keller's framing shifted anything for you?
Week 14: Chapter 12 — The (True) Story of the Cross
Read Chapter 12 of The Reason for God by Timothy Keller.
1.Many people find the doctrine of the atonement — that Jesus died as a substitute for sinners — morally troubling, even offensive. What is the most common objection you have heard? Before working through Keller's response, try to state the objection as charitably and powerfully as you can.
Week 15: Chapter 13 — The Reality of the Resurrection
Read Chapter 13 of The Reason for God by Timothy Keller. Key passage: 1 Corinthians 15:1–20.
1.Keller quotes Paul's statement in 1 Corinthians 15 that "if Christ has not been raised, your faith is futile." Paul stakes everything on the historical resurrection. How does this differ from a religious worldview that says "it doesn't matter whether it literally happened — the spiritual meaning is what counts"?
Week 16: Review & Reflection
Review The Reason for God by Timothy Keller in its entirety. Consider re-reading key passages or your journal notes from previous weeks.
1.When you wrote down your most pressing question or doubt at the end of Week 1, what was it? Return to it now. How has Keller addressed it — or not? Has your thinking changed, deepened, or stiffened? Be specific.
