I do not always respond to those who simply express their opinions.
Nobody is under my dictatorship, and all have a right to opinions of their own.
It is all just background noise to me.
This time you have invoked Jeremiah 31, which you pick up from v.35.
That deserves a response in my opinion, so I will show you how I have come to understand the chapter.
Jeremiah 31:1-30 is Gods message of comfort to the suffering captives. He tells them of the restoration of Jerusalem at the time of the second temple.
I reject attempts to skip over this restoration to a future restoration, because of the time and circumstances that the message was given.
After v. 31 it gets interesting because the New Covenant is introduced.
This is the New Covenant of Jesus and that is a solid fact because the same verses are re-quoted in Hebrews 8:8-12.
Those that attempt to push this event into the future not only hide the testimony of our Lord, but show their allegiance to a Satanic religion that opposes Him.
The nature of the New Covenant shows that God intends a new and improved way of relating to His people:
31 Behold, the days come, saith the Lord, that I will make a new covenant with the house of Israel, and with the house of Judah:
32 Not according to the covenant that I made with their fathers in the day that I took them by the hand to bring them out of the land of Egypt; which my covenant they brake, although I was an husband unto them, saith the Lord:
33 But this shall be the covenant that I will make with the house of Israel; After those days, saith the Lord, I will put my law in their inward parts, and write it in their hearts; and will be their God, and they shall be my people.
34 And they shall teach no more every man his neighbour, and every man his brother, saying, Know the Lord: for they shall all know me, from the least of them unto the greatest of them, saith the Lord: for I will forgive their iniquity, and I will remember their sin no more.
Now you have picked up the passage immediately after this, where God declares that "If those ordinances (sun moon and stars) depart from before me, saith the Lord, then the seed of Israel also shall cease from being a nation before me for ever" (v.36).
It seems that you think God is speaking of an earthly nation, but He is not.
Heavenly Jerusalem and the Israel of God are realities, and all God's people are citizens of that nation.
There is hope for the Jews who are yet unsaved, but it is in Jesus not in modern Israel.
