Proverbs 22:6 promises that the child trained in the way they should go will return to it when old. This is a general principle, not a mechanical guarantee. But it frames the investment of faithful parenting as something that outlasts the rebellion. The Hebrew word for "train" β chanak β means to create the first taste, to initiate into. What was put in does not disappear during rebellion. It is the thing the prodigal remembers when he "came to himself" β the memory of the father's house.
Luke 15:11β32, the parable of the prodigal son, describes two responses to a rebellious child: the father who waited and ran, and the elder brother who kept records. Jesus told both stories. The father's response β running, embracing, celebrating without prior conditions β is the model. The elder brother's response β accurate record-keeping of the wrong done β is the failure mode. Parents of rebellious teens are more vulnerable to the elder brother's temptation than they realize.
