This was truly a great book. It is one of those books that needs to be reread. I plan to do that. A great quote (there were many) is "Jesus is the light of the world. Living near him is the brightest place in the universe. To find out where he lives, read the gospels and follow his path." The main focus of the book is fasting/going without food in order to hunger for God. An intimate relationship with God is worth it! If you want a more intimate relationship with God, I recommend this book. In fact, I recommend many of the books written by John Piper!
