“Then God saw their actions — that they had turned from their evil ways — so God relented from the disaster He had threatened to do to them. And He did not do it.”
Jonah 3:10 HCSB
I read this and am reminded of how, in the gospels, Jesus tells His generation that the only sign they will receive is the sign of Jonah, meaning He will be buried for three days and then will be raised from the dead. Jonah was three days in the belly of the fish before coming ashore. The people of Nineveh listened to God’s word and repented, and were saved.
