Judgement is coming to Nineveh. They were once mighty, and once repented, but all will be destroyed—completely. This prophesy was fulfilled perfectly. Nineveh, which was once a great city, is now just and archeological dig.
Jonah introduced the concept of “Thinking Like a Christian.” Specifically, we saw how to have the right mindset. In Hosea, we’ll learn the right heartset. Hosea gets set up as an example of how God’s love and grace work. Unfortunately for Hosea, that will mean displaying love and grace in tough situations (just like God does).
God calls Jonah to preach repentance to a people he doesn’t particularly care for. He refuses to do it and runs away and boards a ship for Tarshish. That doesn’t work any better than we’d expect, and he ends up getting tossed into the sea. Eventually, Jonah finds himself in the stomach of a fish. Now he has time to think.
