'To me the finest text of Scripture on parenting is the parable of the prodigal son (Luke 15). Here a father, whose sons are both wayward, demonstates wise parenting. We are prone to identify only the younger sons as "prodigal." We are quick to see blatant rebellion and label it as sin. But if our children don't break the rules and maintain an active presence in the church, we are satisfied. We think we have done our job. The parable reminds us that there is a more sinister sin of the heart than active rebellion, passive rebellion.'
