Keller’s book is the most complete book on prayer I’ve ever read. As you read, you quickly realize that Keller is a great deal smarter than you’ll ever be. His humility and skill in communicating, however, make his books readable and accessible. Prayer discusses the theology of prayer, it’s history and importance, and also includes practical steps that you can take to help you grow in your prayer life. It’s a book to be read, but also to be referred to multiple times afterward. I’m grateful for Tim Keller, and especially for this incredible book.
