God was more angry with Jonah one of his called for being angry with God for showing the people you mention compassion.
Johna delivered Gods word to there hearts
I take it you understand that.
Its the same as Gods word being delivered by one man Gideon making 10000 men tremble with fear
That's when the people who Johna delivered his message repented.
All tho you probably have that down to just being an act of there own free will.
Well like I told you his will from the begining is inherent in everyone, and even in you right now.
I said it yesterday if a person can choose to sin out of there own free will, dont you think that's telling you there free will lives in the flesh
But yet for some reason that same free will can choose to be saved. Nope enabling grace comes first, such free will has no value to God it lives in the flesh.
One word for you
Listen.
1. Jonah preached the message to Nineveh given to him by God, "Yet forty days, and Nineveh shall be overthrown."
2. The people of Nineveh believe God, repented, and cried out to God.
3. Verse 10 And God saw their works, that they turned from their evil way; and God repented of the evil, that he had said that he would do unto them; and he did it not.
God was going to overthrow them in forty days. That's what he said. Nineveh repented. God did not overthrow them as he stated.
