Will Israel be Saved?
Rom 11:25-27 I do not want you to be ignorant of this mystery, brothers, so that you may not be conceited: Israel has experienced a hardening in part until the full number of the Gentiles has come in. And so all Israel will be saved, as it is written: "The deliverer will come from Zion; he will turn godlessness away from Jacob. And this is my covenant with them when I take away their sins." (Is 59:20,21; 27:9)
People who become very religious characteristically tend towards a proud elitist attitude. Who did Jesus most commonly characterize as proud but the religious elite. And who were the primary individuals planning Jesus' death but the religious elite. So also throughout the history of post-Biblical institutional Christianity. The very religious tend to be very conceited. And just as the Eleven and other Jewish Christians had been prejudice against Gentiles, so also Christianity having been established among the Gentiles, the Gentiles tend to disregard the Jews.
There will come a time when all Israel at that given time will be saved - not all of Israel of all times, but the Israel which exists at the end. Can Jews be saved apart from faith in Christ? Does God at some point lift His requirement of faith? No. It should be obvious from this and other chapters in Romans that to be saved under the New Covenant a person must believe in Jesus. Rather what Paul is saying that there will come a time when the Jews as a nation will come to believe in Christ.“On that day I will set out to destroy all the nations that attack Jerusalem. And I will pour out on the house of David and the inhabitants of Jerusalem a spirit of grace and supplication. They will look on me, the one they have pierced, and they will mourn for him as one mourns for an only child, and grieve bitterly for him as one grieves for a firstborn son." Zec 12:9,10 And so it also says of Christ's return, "Look, he is coming with the clouds, and every eye will see him, even those who pierced him; and all the peoples of the earth will mourn because of him. So shall it be! Amen.” Rev 1:7
And as with all who put their faith in Christ, the Lord covenants, “I will forgive their wickedness and will remember their sins no more.” Heb 8:12
