“If you will not listen to me, to walk in my law that I have set before you, and to listen to the words of my servants the prophets … I will make this city a curse" (v4-6). Jeremiah’s prophecies weren’t unchangeable announcements of judgment. God was warning His beloved people and giving them a choice. Years earlier, Micah’s prophecies had led to national repentance (v19). But now “the priests and the prophets and the people” wanted to kill Jeremiah (v8), just like the prophet Uriah was murdered (v23).
“Now therefore mend your ways and your deeds” (v13). God warns us because He loves us. He doesn’t want us to face judgment and so calls us to repentance.
