Summary

In this intimate and wide-ranging conversation, Kathy Keller speaks with Luke Martin about life, faith, and the theological vision she shared with her late husband, Tim Keller. Kathy revisits her teenage correspondence with C.S. Lewis, the formative influences that shaped Tim’s preaching, and why “contextualisation” has been so widely misunderstood. She introduces Tim’s new posthumous book, What Is Wrong with the World?, drawn from long-forgotten sermon manuscripts exploring the many disguises of sin. Kathy reflects movingly on grief, idolatry, the hope of the gospel, and why, as she puts it, “you were built to run on God.” She also explains why the idea of sin has become “the last taboo” in today’s culture — and why rediscovering it is essential for understanding ourselves and our world. A thoughtful and heartfelt conversation with the person who knew Tim Keller best.
