It doesn't matter how much we know about God's forgiveness, unless we have had a personal experience with it. The story of Jonah and the Ninevites reveals to us what it means to encounter God's forgiveness personally versus encountering God's forgiveness from a distance. Jonah could "wow" the people with his theological insight to God's forgiveness. But the story ends before we can find out whether or not he truly received God's forgiveness for himself.
