Romans 9:21

Given that our nature sinned in paradise, we are now formed through a mortal begetting by the same divine providence, not according to heaven but according to earth, i. e., not according to the spirit but according to the flesh, and we have all become one mass of clay, i.e., a mass of sin.

If this lump of clay were of such indifferent value that it deserved nothing good any more than it deserved anything evil, there would be reason to see injustice in making of it a vessel unto dishonor. But when through the free will of the first man alone, condemnation extended to the whole lump of clay, it is undoubtedly true that if vessels are made of it unto honor, it is a question not of justice not forestalling grace, but of God's mercy. If however, vessels are made of it unto dishonor, this is to be attributed to God's justice, not to his injustice—a concept which can hardly exist with God!

If both the saved and the lost come from one lump of clay, then the nature of their souls will be not different but the same.

Whoever heard of a clay pot made for menial use blaming the potter for the way it was made and demanding to be remolded for some better purpose?

The vessel is the flesh, because it was made of clay by the breath of God, and only afterward was it clothed with the coat of skin.

Those who are called vessels for menial use have chosen this path for themselves.… This is clear from what Paul says to Timothy: "If anyone purifies himself from what is ignoble, then he will be a vessel for noble use, consecrated and useful to the …

Do not dare to condemn God or imagine that he showed mercy on one and hardened another by accident, for it was according to the power of his foreknowledge that he gave each one his due. Nor is he guilty because he knew in advance …

It is not possible to say on the basis of this [verse] that there are different types of human nature, nor does holy Scripture claim that some people have been made cruel or obdurate or even vessels of honor and wickedness, nor does it attribute this kind of nature to them. Rather, it should be understood to mean that some men are made like clay vessels and that we use them either for honor or for dishonor.

"Nay but, O man, who art thou that repliest against God?" This he does to take down the objector's unseasonable inquisitiveness, and excessive curiosity, and to put a check upon it, and teach him to know what God is, and what man, and how incomprehensible His foreknowledge is, and how far above our reason, and how obedience to Him in all points is binding. So when he has made this preparatory step in his hearer, and has hushed and softened down his spirit, then with great felicity he introduces the answer, having made what he says easy of admittance with him. And he does not say, it is impossible to answer questions of this kind, but that it is presumptuous to raise them. For our business is to obey what God does, not to be curious even if we do not know the reason of them. Wherefore he said, "Who art thou that repliest against God?" You see how very light he makes of him, how he bears down his swelling spirit! "Shall the thing formed say to Him that formed it, Why hast Thou made me thus? Hath not the potter power, of the same lump to make one vessel unto honor, and another unto dishonor?" Here it is not to do away with free-will that he says this, but to show, up to what point we ought to obey God. For in respect of calling God to account, we ought to be as little disposed to it as the clay is. For we ought to abstain not from gainsaying or questioning only, but even from speaking or thinking of it at all, and to become like that lifeless matter, which followeth the potter's hands, and lets itself be drawn about anywhere he may please. And this is the only point he applied the illustration to, not, that is, to any enunciation of the rule of life, but to the complete obedience and silence enforced upon us. […]

Then the Apostle explains the words of the prophet, when he says or has not the potter power. As if to say what is molded, i.e., the vessel, should not say to the potter: why have you made me thus? because the potter is free …

As a potter makes whatever he pleases from one and the same clay, and not one of the vessels contradicts him, so you too should not ask God why He punishes some people and rewards others, even though they are of one and the same …

He wills nothing but what is infinitely wise and good; and therefore his will is a most proper rule of judgment. He will show mercy, as he hath assured us, to none but true believers, nor harden any but such as obstinately refuse his mercy.

The potter, out of the same lump, may make either a fashionable vessel, and a vessel fit for creditable and honourable uses, or a contemptible vessel, and a vessel in which is no pleasure; and herein he acts arbitrarily, as he might have chosen whether he would make any vessel of it at all, or whether he would leave it in the hole of the pit, out of which it was dug.

Hath not the potter power over the clay,....

All are sinners, and have forfeited every claim to His mercy; it is therefore perfectly competent to God to spare one and not another, to make one vessel to honor and another to dishonor. But it is to be borne in mind that Paul does not here speak of God's right over His creatures as creatures, but as sinful creatures: as he himself clearly intimates in the next verses.

Hath not the potter power over the clay - The apostle continues his answer to the Jew. Hath not God shown, by the parable of the potter, Jer 18:1, etc., that he may justly dispose of nations, and of the Jews in particular, according as he in his infinite wisdom may judge most right and fitting; even as the potter has a right, out of the same lump of clay, to make one vessel to a more honorable and another to a less honorable use, as his own judgment and skill may direct; for no potter will take pains to make a vessel merely that he may show that he has power to dash it to pieces? For the word came to Jeremiah from the Lord, saying, Arise, and go down to the potter’s house, and there I will cause thee to hear my words. Then I went down to the potter’s house, and, behold, he wrought a work upon the wheels. And the vessel that he made of clay was marred in the hands of the potter: so he made it again another vessel, as seemed good to the potter to make it. It was not fit for the more honorable place in the mansion, and therefore he made it for a less honorable place, but as necessary for the master’s use there, as it could have been in a more honorable situation. Then the word of the Lord came to me, saying, O house of Israel, cannot I do with you as this potter? Behold, as the clay is in the potter’s hand, so are ye in mine hand, O house of Israel. At what instant I shall speak concerning a nation, and concerning a kingdom, to pluck up, and to pull down, and to destroy it; 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. And at what instant I shall speak concerning a nation - to build and to plant it; is 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. […]

Hath not the potter ... - This same sovereign right of God the apostle proceeds to urge from another illustration, and another passage from the Old Testament; Isa 64:8, “But now, O Lord, thou art our Father; we are the clay, and thou our potter; and we all are the work of thy hand.” This passage is preceded in Isaiah by one declaring “the depravity of man;” Isa 64:6, “We are all as an unclean thing, and all our righteousnesses are as filthy rags; and we all do fade as a leaf; and our iniquities, like the wind, have taken us away.” As they were polluted with sin, as they had transgressed the Law of God, and had no claim and no merit, God might bestow his favors as he pleased, and mould them as the potter did the clay.
