In Jonah 3-4, the entire city of Nineveh repents at Jonah's preaching, demonstrating one of the most remarkable mass conversions in the Old Testament and anticipating the gospel going out to all nations in the new covenant. Jonah's furious response to God's mercy on Nineveh exposes a deep spiritual problem common to those who have received God's grace but resent it being extended to their enemies. God uses the object lesson of the plant and the worm to confront Jonah's selfishness, showing that everything we have is a gift of mercy, and our comforts should not blind us to the spiritual need of those around us. The book closes with God's unanswered question — "Should I not pity Nineveh?" — as a perpetual challenge to the church to care about the lost as God does, rather than retreating into creaturely comfort. Christ is the true and better Jonah who willingly descended into death for sinners and rose again with the commission to make disciples of all nations, and remembering that grace is what fuels genuine mission-mindedness.
