Jeremiah 18:8

If that nation, against whom I have pronounced, turn from their evil; if that nation leaveth off those sinful courses which I have by my prophets threatened with judgments; I will repent of the evil that I thought to do unto them; I will also turn from the methods of my severe providence which I had resolved in case of their impenitency to proceed in against them. There is a difference betwixt repentance in man, and repentance as it is attributed to God; repentance in man must be, not only a change in action, but a change of heart; repentance as attributed to God never signifieth a change of heart, or purpose, or counsels, but only a change in action, all alteration of the course of his providence. Hence God in Scripture is said to repent, as in this text, and Jonah 3:10. And it is also said of him, that he is not as man, that he should lie or repent, Numbers 23:19 1 Samuel 15:29. God never changeth his counsels or purposes, though he often varieth his actions of providence, according to the behaviours of his creatures.
