Pastor Tim Keller writes an apologetic book for the ages. The first half of the book deals with issues that keep people from believing in Christianity, such as "Why is there only one way to God?", "How can a loving God send people to Hell?", and "Hasn't Science disproved Christianity?". The second half of the book Keller gives reasons for believing in Christianity.
The footnotes are also incredible, allowing a person to dig deeper into an issue if they want.
This book is just brilliant. Keller pulls from his experience as a pastor in New York City. He has the pulse of what the seeker may ask or want to know. At several points in the book, one can detect he is taking aim at several of the new atheist books that have recently hit the market. However, he writes in a fair, gracious, and winsome style. This book will benefit both the seeker and believer as it gives one a greater confidence in the truth of God.
