Deuteronomy 6:7 remains the core of Biblical parenting instruction: "thou shalt teach them diligently unto thy children, and shalt talk of them when thou sittest in thine house, and when thou walkest by the way, and when thou liest down, and when thou risest up." The Hebrew shanan β diligently β means to engrave, to sharpen, to press in repeatedly. Formation is not a program you run; it is the texture of ordinary life together. You cannot outsource it to youth group.
But Moses gave this command to a generation of Israelites who were about to enter Canaan β and whose children would grow up to worship the Baals within two generations. The Deuteronomy mandate did not prevent the book of Judges. Faithful transmission is the calling. The reception is not fully within any parent's control. This is not an excuse to give up β it is a release from the assumption that your teenager's choices are entirely a report card on your parenting.
Jesus' parable of the prodigal son (Luke 15) is almost always read from the son's perspective. But it is also a portrait of a father who had done everything right β and watched his son take his inheritance and waste it anyway. The father doesn't chase him, doesn't manipulate him back, doesn't negotiate. He lets him go. He watches. And when the son "came to himself" and turned for home, the father saw him from a long way off β meaning he was looking β and ran. You cannot compel faith. You can keep watching for its return.
