One can’t imagine better English words could be used to express this truth.
Jer 18:1 The word which came to Jeremiah from the LORD, saying,
Jer 18:2 Arise, and go down to the potter’s house, and there I will cause thee to hear my words.
Jer 18:3 Then I went down to the potter’s house, and, behold, he wrought a work on the wheels.
Jer 18:4 And the vessel that he made of clay was marred in the hand of the potter: so he made it again another vessel, as seemed good to the potter to make it.
Jer 18:5 Then the word of the LORD came to me, saying,
Jer 18:6 O house of Israel, cannot I do with you as this potter? saith the LORD. Behold, as the clay is in the potter’s hand, so are ye in mine hand, O house of Israel.
Notice how God responds in an “instant”.
Gill writes:;
At what instant I shall speak concerning a nation, and concerning a kingdom,…. By way of threatening: or, “the moment I shall speak” (s), &c; as soon as ever I have declared concerning any people whatever, Jews or Gentiles; that if they go on in their sins, and remain impenitent, and do not turn from them, that they must expect I will quickly come out against such a nation and kingdom in a providential way, as threatened:
And at what instant I shall speak concerning a nation, and concerning a kingdom,…. By way of promise on the other hand: or, “and the moment I shall speak”, &c. as in Jer 18:7; in favour to a people; signifying, that if they do that which is right and good, and continue therein, it may be expected that I will appear for and among such a nation and kingdom:
Jer 18:7 At what instant I shall speak concerning a nation, and concerning a kingdom, to pluck up, and to pull down, and to destroy it;
Jer 18:8 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.
Jer 18:9 And at what instant I shall speak concerning a nation, and concerning a kingdom, to build and to plant it;
Jer 18:10 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.
Jer 18:11 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.
