If only Jonah would have ended happily ever after in chapter 3, but instead realistically ends (sort of) in chapter 4 were Jonah reveals his real reason for not wanting to go to Nineveh. The way that Jonah ends helps all of us to take a hard look in mirror of our sin but even more so assures us of our Lord God who will never give up on his prophets or his people always inviting them to repent and receive what nobody deserves grace, mercy, and forgiveness.
