God sends two prophets to plead with Israel and Judah to turn back to Him: Jonah; Amos
Sent to Nineveh to preach repentance, Jonah saw first hand how God could forgive even foreigners and hold back threatened judgement.
Jonah wasn’t happy about it:
Jonah 4:2- So he complained to the Lord about it: ‘Didn’t I say before I left home that you would do this, Lord? That is why I ran away to Tarshish! I knew that you are a merciful and compassionate God, slow to get angry and filled with unfailing love. You are eager to turn back from destroying people. ‘Just kill me now, Lord! I’d rather be dead than alive if what I predicted will not happen.’
