Both Jeremiah and Paul (Romans 9) used the potter and clay metaphor to explain God’s sovereignty and Israel’s sin. The potter stands as judge over his own creation. If he finds a flaw in it, he is free to remake it according to his wishes. Yet Jeremiah also makes it clear that the judgment works both ways. At any time, if Israel repents, then the LORD will relent his plans to destroy it. The prophecy is conditional.
But Jeremiah has had enough. The plotting to kill him was the last straw for him. He prayed to the LORD not to forgive them, but to let them be overthrown. He expresses the anger that God feels at a rebellious people.
