Author: Timothy KellerTimothy Keller uses one of the best-known Christian parables to reveal an unexpected message of hope and salvation. Taking his trademark intellectual approach to understanding Christianity, Keller uncovers the essential message of Jesus, locked inside his most familiar parable. Within that parable Jesus reveals God's prodigal grace toward both the irreligious and the moralistic. This book will challenge both the devout and skeptics to see Christianity in a whole new way.
