Absolutely all of Israel being saved is irrational since we all know man is saved by his works and not by his nationality.
This post is a compendium of very serious errors. First, after being shown repeated scriptures explicitly stating that absolutely all of Israel will be saved, you answer that this is irrational.
This is blatant unbelief.
Next, after denying that what God explicitly said by saying it was irrational, you went on the say exactly the opposite of what God explicitly says in other places.
You say that "we all know man is saved by his works." But the scriptures very plainly say that it is "not by works of righteousness which we have done, but according to His mercy He saved us."
Titus 3:5
Again, we read that "a man is not justified by the works of the law but by faith in Jesus Christ, even we have believed in Christ Jesus, that we might be justified by faith in Christ and not by the works of the law; for by the works of the law no flesh shall be justified."
Galatians 2:16
And "by grace you have been saved through faith, and that not of yourselves;
it is the gift of God, not of works, lest anyone should boast."
Ephesians 2:8-9
This point is vastly more important than eschatology. For anyone and everyone who is trusting in his or her own works to get to heaven is not on their way there at all.
The "all of Israel" being saved is referencing the 1st resurrection, when "all" the righteous will be saved, the separation of the sheep from the goats.
All Jews are not saints. That's just common sense.
I don't seem how some base their whole belief on one singular verse.
I have given you scripture after scripture which explicitly state what I am saying, and state it in very plain words. And you try to toss it all of as basing my "whole belief on one single verse"?
Your entire argument is based on assumptions, interpretations, and ignoring what God has explicitly said. Of course the Jews are not saints. That is why God will bring them to repentance. You claim that this is only my interpretation. But it is not. It is what God has plainly said, in some of the scriptures I quoted and in many others. The fact that you choose to not believe this does not make believing it "my interpretation."
I will again, and unequivocally, state that simply believing the scriptures is not interpreting them. You are interpreting the scriptures. I am believing them.
