Timothy Keller’s new book The Prodigal God: Recovering the Heart of the Christian Faith. Keller targets both seekers who are unfamiliar with the gospel and longtime church members who may not feel the need for a primer on the gospel. Keller’s book, as the provocative title suggests, is built on one of Jesus’ most famous stories: the parable of the prodigal son (Luke 15). Keller consents that “on the surface of it, the narrative is not all that gripping.” But, he contends that “if the teaching of Jesus is likened to a lake, this famous Parable of the Prodigal Son would be one of the clearest spots.

The book is laid out in seven brief chapters which aim to uncover the extravagant (prodigal) grace of God, as revealed in this parable. Keller shows how the parable describes two kinds of “lost” people, not just one. Most people can identify the lostness of the “prodigal son,” the younger brother in Jesus’ story, who takes his inheritance early and squanders it on riotous living. But Keller shows that the “elder brother” in the parable is no less lost.

Together, the two brothers are illustrations of two kinds of people in the world. “Jesus uses the younger and elder brothers to portray the two basic ways people try to find happiness and fulfillment: the way of moral conformity and the way of self-discovery.”
As with Keller’s preaching, this book is intelligent and winsome, combining thoughtful reflection on both text and culture with searching heart application. Keller’s book is effectively illustrated with a liberal use of stories and quotations from literature, movies, and the arts. Most imporantly, the book orients the reader’s heart to the hope of the gospel of God’s grace revealed in Christ.
