Because Jesus' critics do not understand what God is like, He gives them three parables to challenge their wrong understanding. In the first two, He recounts the joy one feels when something valuable is lost and then found. The third is the parable of the prodigal son, which actually is about the grace and mercy the father has for not only his reprobate son who, after squandering his inheritance, returns repentant, but also for the ungrateful son who remained behind.
