Jeremiah 31
"37 Thus says the Lord:
“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, says the Lord."
God WILL NOT reject Israel, as you see above. And the key term is there... I will also cast off
all the seed of Israel. Israel is the chosen people of God, and will always be, however, when the plan of redemption comes to a close, it will be the church, made up of Jews and Gentiles. All will be one. God will finally have shown mercy to all, as Paul says. Why do you hate the idea of the remnant of Israel being shown mercy? You do understand Paul wrote those chapters of Rome to stop those in the church from adopting that kind of thinking, right?
Romans 9
"25 As He says also in Hosea:
“I will call them My people, who were not My people,
And her beloved, who was not beloved.”
26 “And it shall come to pass in the place where it was said to them,
‘You
are not My people,’
There they shall be called sons of the living God.”
27 Isaiah also cries out concerning Israel:
“
Though the number of the children of Israel be as the sand of the sea,
The remnant will be saved.
28 For [
b]He will finish the work and cut
it short in righteousness,
Because the Lord will make a short work upon the earth.”
29 And as Isaiah said before:
“Unless the Lord of [c]Sabaoth had left us a seed,
We would have become like Sodom,
And we would have been made like Gomorrah.”"
Romans 11
"11 I say then,
have they stumbled that they should fall?
Certainly not! But
through their [b]fall, to provoke them to jealousy, salvation has come to the Gentiles. 12
Now if their [c]fall is riches for the world, and their failure riches for the Gentiles, how much more their fullness!"
" 24 For
if you were cut out of the olive tree which is wild by nature, and were
grafted contrary to nature into a cultivated olive tree,
how much more will these, who are natural branches, be grafted into their own olive tree?" Even Paul supports the two different programs. However, even he seems to understand that in the end all are one, as there is only one olive tree. But again, even Paul treats them separate. One foreign, one natural, one from an olive tree that is wild by nature, and one from a cultivated olive tree. Paul gives no quarter for a gentile who manages to get cut off the tree after being grafted in. Full quarter is given to Jews who turn back to God, and come to faith.
Why? Two different groups of people. Jews and Gentiles, enemies from birth until Jesus put to death the emnity in His body. Yet, still two groups, just one in the body of Christ. In the church, brothers and sisters. Outside of the church, our enemies in the gospel, though brothers and sisters in life. You see this handling throughout all of scripture... except at the end. In the end, all are one. All have reached the end of their journey and reached the goal. The unsaved remnant of Israel will finally be saved and enter in their rest in Him. Or,what you say is true, and they are shut out of God's presence forever.
