Tim Keller’s name is known across the evangelical world. His work as a pastor-teacher has found expression both in the urban ministries of Redeemer Presbyterian Church in New York, and in his many writings. Keller’s books, in turn, have spawned Bible study courses and generated a great measure of discussion about key biblical concepts, as he has sought to make the gospel relevant for a modern generation. In this collection of essays, written from within the same evangelical constituency, several writers engage with different aspects of Keller’s though. While indebted to Keller in many ways, they also wish to examine his position in the light of Scripture and to work constructively as well as critically with his published works. That such an influential figure should be the subject of discussion is not surprising; what will be surprising to many is that not all evangelicals are prepared to accept without question all of Keller’s conclusions or formulations. This is a book to stimulate discussion and to remind us that God’s Word must always be our final judge in matters of theology, evangelism and apologetics.
