Erlo Stegen preaches on the parable of the prodigal son, emphasizing the foolishness of the younger son who demanded his inheritance and squandered it on reckless living. He warns parents about the dangers of leading their children astray and the importance of guiding them in the ways of the Lord. The sermon highlights the consequences of disobedience and the need for repentance, as the younger son eventually returns to his father seeking forgiveness. Stegen contrasts the father's compassion with the older brother's resentment, urging listeners to reflect on their own attitudes towards grace and forgiveness. Ultimately, he calls for a commitment to obedience and respect for parental authority.
