A thoughtful reading of Jonah can raise an interesting question. Are we more ready to condemn sinners than God is? While God wanted to show compassion on the people of Nineveh, Jonah wanted their destruction. When God wanted to call them to repentance, Jonah wanted them to remain in their sins and die.
One of the problems was that Jonah wanted God to bless his own nation of Israel and nobody else. Jonah was not prepared to love his enemies, even though God was. Are you more like Jonah or more like God? Are you prepared to love your enemies? Are you prepared to pray blessings on your enemies? Are you prepared to act on their behalf? Or would you rather they "get what they deserve"?
God gave what we deserve to Christ, so that he could give us the blessings Christ deserves. Will you take that message to your personal Nineveh?
