To most, Jonah is all about him getting swallowed by a big fish, but the theme of his book is so much more. In these 4 chapters, Jonah offers three deep principles to our humanity: our deepest issue, our deepest frustration, and our deepest hope. Ultimately, Jonah's life would be a precursor to the Messiah that would come and would be in the grave three days and three nights, who would be the greatest source of hope to all of humanity.
