About This Study Guide

At a glance: this is a 16-week study and discussion guide for The Reason for God by Timothy Keller, with 112 questions organized by reading assignment. Week 1 is free to read, with no card required.

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.

Introduction — The Leap of Doubt

Free — no card
Open Week 1

Read the Introduction of The Reason for God by Timothy Keller

Keller opens by arguing that both faith and doubt require a leap — and that the real question is not whether you will commit to something, but what you will commit to. Sit with that challenge as you consider these questions.

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?

A note from the founder: I’m Josh, and I built this because most Christian books don’t come with study materials — leaving volunteer leaders to build discussion questions from scratch on a Saturday night. That shouldn’t be the default. If anything about your guide isn’t right, reply to your order email and it comes straight to me.
