Tim Keller has written one of the most clarifying books that I have ever read on the heart of Jesus message. It is accessible to someone just beginning to think about the gospel and a clear and thought provoking read for the mature believer. More than an explanation of one of Jesus parables, The Prodigal God is a journey into the subtleties of the human heart making distinctions between religious discipline and worship, prideful self-salvation and true repentance. In speaking of the teaching of the parable Keller says:
"This means that you can rebel against God and be alienated from him either by breking the rules [like the younger son] or by keeping them diligently [like the older son]. It's a shocking message: Careful obedience to God's law may serve as a strategy for rebelling against God."
At approximately 130 small pages it is a quick read that communicates more than most books do in 500 pages. As you can tell, I highly recommend you put this one on the reading list. Thanks to Dave and Nancy Fauth for providing us with this fine reading material.
