A look at the Structure of those verses, as well as a comparison with the events leading up to the Day of the Lord might shed some light. Remember that there is no punctuation, or division into verses in the MSS.
I will highlight, in red, items "C" for the comparison.
Jeremiah 14:7 - 15:24 INTERCESSION
(Extended Alternation)
A. 14:7-9. Deprecation. Jeremiah.
B. 14:10-12. Rejection. Yahoveh.
C. 14:13-18. Prophets. (False)
A. 14:19-22. Deprecation. Jeremiah.
B. 15:1-9. Rejection. Yahoveh.
C. 15:10-21. Prophets. (True)
Concerning the true prophets, only a remnant, those who return to Yahoveh...that is,
in truth...shall save themselves alive.
(2 Th 2:10-12) And with all deceivableness of unrighteousness in them that perish; because they received not the love of the truth, that they might be saved. {11} And for this cause God shall send them strong delusion, that they should believe a lie: {12} That they all might be damned who believed not the truth, but had pleasure in unrighteousness.
By Hebrew idiom, God does what a person
allows to be done. If people choose to listen to the false prophets, then their prayers, their hymns, their tithes, their ice-cream socials, and all there works are emptiness.
God doesn't listen to or accept them, because they are listening to or accepting lies in His Name.
(Mat 7:22-23) Many will say to me in that day, Lord, Lord, have we not prophesied in thy name? and in thy name have cast out devils? and in thy name done many wonderful works? {23} And then will I profess unto them, I never knew you: depart from me, ye that work iniquity.
As a side note, here's a reference in Jeremiah and Revelation:
(Jer 15:2) And it shall come to pass, if they say unto thee, Whither shall we go forth? then thou shalt tell them, Thus saith the LORD; Such as are for death, to death; and such as are for the sword, to the sword; and such as are for the famine, to the famine; and such as are for the captivity, to the captivity.
(Rev 13:10) He that leadeth into captivity shall go into captivity: he that killeth with the sword must be killed with the sword. Here is the patience and the faith of the saints.
These are Hebrew idioms for destiny.
