Jonah 3:10 Then God saw their [the people of Nineveh] 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.
God brings evil people to repentance, and He still forgives when they turn to Him. Trust that God is still in the business of transforming wicked people through the preaching of the Word and the prayers of HIs people. Preach and teach passionately in the light of that truth today.
