I won't chase your errors around. They are too extensive. But consider this at least: The word used in Jer2:19 is not the "fear" of the Lord used in Jer32:40 or Prov1:29. The fear of the Lord is discussed in Scripture many times' long before Jeremiah and is not just a NC promise. The lasting fear of the Lord in Jer32 re: the NC in Jer31 is just that, covenantal. The instruction about the volition of the people can be seen at minimum in Jer31:15 and on. The participants in the NC are ultimately those who responsively, volitionally believe in God.
