Sometime about 2 decades or so ago I was looking up the verse about the leopard not changing his spots and I happened upon this passage.
Some folks argue that "It is not God's will that any should perish" so that means all mankind will be saved no matter what because nothing man can do will cause God's will to not be done."
.....But note this passage from Jeremiah. God said “I have caused to cleave” That word is הדבקתי/ha’dabaq’thi. It is in the perfect or completed sense. God’s express will, clearly stated, for the whole house of Israel and Judah, to cling to God as a belt clings to a man’s waist. It was done, finished, completed, in God’s sight, and, according to some arguments, nothing man can do will cause God’s will to not be done. But they, Israel and Judah, would not hear and obey, their will, vs. God’s will, So God destroyed them, vs. 14.
…..This passage very much speaks to God’s sovereign will, and man’s free will and agency. God stated very clearly what His will was, in terms that cannot be misunderstood. But, because the Israelites and Judeans would not hear, and obey, God destroyed them, instead of them being unto God, “for a people, and for a name, and for a praise, and for a glory, vs. 10.”
Jer 13:1 Thus saith the LORD unto me, Go and get thee a linen girdle, and put it upon thy loins, and put it not in water.
2 So I got a girdle according to the word of the LORD, and put it on my loins.
3 And the word of the LORD came unto me the second time, saying,
4 Take the girdle that thou hast got, which is upon thy loins, and arise, go to Euphrates, and hide it there in a hole of the rock.
5 So I went, and hid it by Euphrates, as the LORD commanded me.
6 And it came to pass after many days, that the LORD said unto me, Arise, go to Euphrates, and take the girdle from thence, which I commanded thee to hide there.
7 Then I went to Euphrates, and digged, and took the girdle from the place where I had hid it: and, behold, the girdle was marred, it was profitable for nothing.
8 Then the word of the LORD came unto me, saying,
9 Thus saith the LORD, After this manner will I mar the pride of Judah, and the great pride of Jerusalem.
10 This evil people, which refuse to hear my words, which walk in the imagination of their heart, and walk after other gods, to serve them, and to worship them, shall even be as this girdle, which is good for nothing.
11 For as the girdle cleaveth to the loins of a man, so have I caused to cleave [הדבקתי/ha’dabaq’thi] unto me the whole house of Israel and the whole house of Judah, saith the LORD; that they might be unto me for a people, and for a name, and for a praise, and for a glory: but they would not hear. . .
14 And I will dash them one against another, even the fathers and the sons together, saith the LORD: I will not pity, nor spare, nor have mercy, but destroy them.
Note, verse 14, God said "I will NOT have pity, will NOT spare, and will NOT have mercy but destroy them."
