Jer 31:34 And they shall teach no more every man his neighbour, and every man his brother, saying, Know the YHWH: for they shall all know me, from the least of them unto the greatest of them, saith YHWH: for I will forgive their iniquity, and I will remember their sin no more.
Jer 31:35 Thus saith YHWH, which giveth the sun for a light by day, and the ordinances of the moon and of the stars for a light by night, which divideth the sea when the waves thereof roar; YHWH of hosts is his name:
Jer 31:36 If those ordinances depart from before me, saith YHWH, then the seed of Israel also shall cease from being a nation before me for ever.
Jer 31:37 Thus saith YHWH; If heaven above can be measured, and the foundations of the earth searched out beneath, I will also cast off all the seed of Israel for all that they have done, saith YHWH.
Jer 31:38 Behold, the days come, saith YHWH, that the city shall be built to YHWH from the tower of Hananeel unto the gate of the corner.
Jer 31:39 And the measuring line shall yet go forth over against it upon the hill Gareb, and shall compass about to Goath.
Jer 31:40 And the whole valley of the dead bodies, and of the ashes, and all the fields unto the brook of Kidron, unto the corner of the horse gate toward the east, shall be holy unto YHWH; it shall not be plucked up, nor thrown down any more for ever.
I see nothing in the rest of the chapter that addresses what is written in hearts and minds under the New Covenant. Let's cease with the guessing games and just say what you are believing.
