Session Guide
Each session includes a video teaching, Scripture references, group discussion questions, and key insights from C.S. Lewis.
Session 1: Our Sense of Right and Wrong
📘 Book 1: Chapters 1–2
We begin where Lewis begins—with the universal sense of morality. Why do all people everywhere appeal to some standard of right and wrong?
Session 2: What’s Behind Our Sense of Right and Wrong
📘 Book 1: Chapters 3–5
If morality is real, then what’s its source? Lewis explores the clues behind the universe and our uneasy conscience.
Session 3: The Rival Conceptions of God
📘 Book 2: Chapters 1–2
Christianity doesn’t reject all other faiths, but it insists on certain truths. Lewis explores pantheism, dualism, and Christian theism.
Session 4: Free Will and The Shocking Alternative
📘 Book 2: Chapters 3–5
Why did God give us free will, knowing we’d use it to rebel? And what does Christ’s death actually mean?
Session 5: Christian Behavior and The Great Sin of Pride
📘 Book 3: Chapters 1–9
Morality isn’t just about behavior—it’s about becoming like Christ. Lewis walks us through the virtues, vices, and the root sin of pride.
Session 6: The Christian Hope
📘 Book 3: Chapters 9–12
Hope is not wishful thinking. It’s a central Christian virtue. This session unpacks the biblical doctrine of eternal life and sanctification.
Session 7: God in Three Persons
📘 Book 4: Chapters 1–8
The Trinity isn’t theological confusion—it’s the key to understanding the life of God. Discover how the doctrine of God’s triune nature invites us into relationship and transformation.
Session 8: Counting the Cost
📘 Book 4: Chapters 9–11
Becoming a Christian means dying to self—and rising in Christ. Lewis ends with a call to transformation, discipleship, and joy.
