Jonah's self-pity so warped his moral sense that he had more compassion for a plant than for a city full of people. Our zeal for the truth, justice, and service of God must always be undergirded by love for and submission to the person of God Himself.
The humanism of our culture is burning out and idle utopian delusions occupy those waiting for the end. While humanism is committing suicide, this is a time of glorious opportunity to bring the saving Gospel of Jesus.
God disciplines us for our good in terms of His call upon our lives, bringing us back to His presence and to His word.
Jonah is a sign that points us to Christ and calls us to godly repentance that leads to life.
We cannot contravene God's calling and equipping of us. If we resist God's will, He often gives us over to our sin. In Jonah's case God used the storm to discipline His prophet.
Jonah's vision for ministry was at odds with Gods vision. As with all rebellion, Jonah's problem with God's call was moral, not intellectual. It is embracing the word and purpose of God that brings life and peace.
