For many, the story of Jonah and the huge fish is a reason to mock the Christian faith. How can a man survive inside the belly of a huge fish for three days and nights? And, why did the Ninevites repent so quickly and so thoroughly? After the fish story, this seems like another logical barrier to taking Jonah seriously. But when we enter the polytheistic world of the Ninevites, it makes a little more sense, and after that, when we remember what Jesus said of their repentance, it not only makes more sense but it's also a gut-check moment for Christians.
