Luke: This is the parable of the Prodigal Son. While the younger son asked for his share of the inheritance, the message being sent to the father was “I wish you were dead.” This act of disrespect on the part of the son to his father is a serious infraction against the 5th Commandment: Honor thy father and thy mother. BTW the older son, because of his anger and bitterness, was no less prodigal because he was so self-righteous.
New Testament: James 1:1-15
Old Testament: Joel 2:21-27
