Jeremiah 18:6

Cannot I do with you as this potter? - Have I not a right to do with a people whom I have created as reason and justice may require? If they do not answer my intentions, may I not reject and destroy them; and act as this potter, make a new vessel out of that which at first did not succeed in his hands?

It is generally supposed that St. Paul has made a very different use of this similitude from that mentioned above. See Romans 9:20, etc. His words are, "Hath not the potter power over the clay, of the same lump to make one vessel unto honor, and another unto dishonor?" To this every sensible and pious man will answer, Undoubtedly he has. But would any potter make an exceedingly fair and good vessel on purpose to dash it to pieces when he had done? Surely no! And would or could, the God of infinite perfection and love make millions of immortal souls on purpose for eternal perdition, as the horrible decree of reprobation states? No! This is a lie against all the attributes of God. But does not the text state that he can, out of the same lump, the same mass of human nature, make one vessel to honor, and another to dishonor? Yes. But the text does not say, what the horrible decree says, that he makes one part, and indeed the greater, for eternal perdition. But what then is the meaning of the text? Why evidently this: As out of the same mass of clay a potter may make a flagon for the table and a certain utensil for the chamber, the one for a more honorable, the other for a less honorable use, though both equally necessary to the owner; so God, out of the same flesh and blood, may make the tiller of the field and the prophet of the Most High; the one in a more honorable, the other in a less honorable employ; yet both equally necessary in the world, and equally capable of bringing glory to God in their respective places. But if the vessel be marred in his hand, under his providential and gracious dealings, he may reject it as he did the Jews, and make another vessel, such as he is pleased with, of the Gentiles; yet even these marred vessels, the reprobate Jews, are not finally rejected; for all Israel shall be saved in (through) the Lord, i.e., Jesus Christ. And should the Gentiles act as the Jews have done, then they also shall be cut off, and God will call his Church by another name. See on Romans 9:22 (note) and below.

So are ye in mine hand - When a vessel was ruined, the potter did not throw it away, but crushed it together, dashed it back upon the wheel, and began his work afresh, until the clay had taken the predetermined shape. It was God's purpose that Judaea should become the proper scene for the manifestation of the Messiah, and her sons be fit to receive the Saviour's teaching and carry the good tidings to all lands. If therefore at any stage of the preparation the Jewish nation took such a course as would have frustrated this purpose of Providence, it was crushed by affliction into an unresisting mass, in which the formative process began again immediately.

18:6 Cannot I do - That God hath an absolute sovereign power to do what he pleases with the work of his hands: but he acts as a just judge, rendering to every man according to his works.
