This father (Luke 15:11-17) knows how reckless and self-destructive his son is being, and he knows his son is going to squander whatever he gives him. So what does he do? He turns everything we think we know about raising responsible children on its head and gives the boy what he asks. We read that and think, What an unwise father. If this father had been steeped in the proverbial wisdom of the Bible, he would have never made such a foolish mistake. But the father knows something we don’t. He knows that in order to win the heart of his son, he has to risk losing him altogether by giving him something even more dangerous and reckless than what he asked for. He has to give him grace.
