Jeremiah's purpose was to call his hearers to repentance in view of God's judgment on Judah, which would come soon from an army from the north (chs. 2-45). Judgment was coming because God's people had forsaken Yahweh and had given themselves to idolatry. Jeremiah spoke more about repentance than any other prophet. He also assured his audience that God had a future for Israel and Judah (chs. 30-33). Once it became clear that the people would not repent, he advocated submission to Babylon to minimize the destruction that was inevitable. As God's prophetic spokesman, he also uttered oracles against the nations that opposed God's chosen people (chs. 46-51).
"The theme of this prophet consists largely in a stern warning to Judah to turn from idolatry and sin to avoid the catastrophe of exile."22
