Jonah did not want to preach the Gospel to the Ninevites and even after he did he wanted them to die. Jonah did not tell the Ninevites that God is known to repent of the evil He pronounces against a nation if they repent of their sin, but the Ninevites found that out for themselves in spite of Jonah's abbreviated message.What in the world are you talking about?!!!
Jonah was NOT a racist and it was not "Jonah's one-sided judgment message" it was GOD's one sided message! It is quite thoroughly recorded right there in the pages of your own bible. One thing was prophesied and something else happened. God changed His mind! The whole point of the story is that it was God who changed His mind! You can rationalize it away all you like but I'm going to stick with the plain reading of God's word while you can stick with your personal opinions and teachings of the men.
P.S. DO NOT under any circumstances read Bob Enyart's book! (Not that your were ever going to anyway.) You're not nearly as honest as I had given your credit for and it would be a waste of your time. You're one who believes what he wants and nothing else.
No prophecy failed.
