The Lord himself explains and applies his type of the Potter. And in Jesus how hath the doctrine been fully proved? Surely the Lord can with infinitely more ease create new hearts in his people, and reform both a people and a nation, by the mere sovereignty of his holy word, than the Potter who worketh on vessels of clay, can new make from the broken portions which are marred. But alas! how sin hardens, so as to make the sinner despair, in spite of God's grace, and the declared purposes of God's love, Jeremiah 2:25.
Jeremiah 18:7-12
7 At what instant I shall speak concerning a nation, and concerning a kingdom, to pluck up, and to pull down, and to destroy it;
8 If that nation, against whom I have pronounced, turn from their evil, I will repent of the evil that I thought to do unto them.
9 And at what instant I shall speak concerning a nation, and concerning a kingdom, to build and to plant it;
10 If it do evil in my sight, that it obey not my voice, then I will repent of the good, wherewith I said I would benefit them.
11 Now therefore go to, speak to the men of Judah, and to the inhabitants of Jerusalem, saying, Thus saith the LORD; Behold, I frame evil against you, and devise a device against you: return ye now every one from his evil way, and make your ways and your doings good.
12 And they said, There is no hope: but we will walk after our own devices, and we will every one do the imagination of his evil heart.
