Since God calls the Jews his chosen people, some folks might say they're all saved. But as we see from the most famous Bible verse, it's whosoever believes on Jesus that are saved.
So if the chosen people weren't chosen to be saved, what does it mean that they were chosen? It was so that the Messiah would be born through the lineage of Abraham. As the Apostle Paul explains in Galatians 3:8 (KJV), "And the scripture, foreseeing that God would justify the heathen through faith, preached before the gospel unto Abraham, saying, In thee shall all nations be blessed."
This shows that the purpose of God to work through Abraham was to lead humanity to salvation. These people are what Paul calls the Israel of God. As he wrote in Galatians 6:16 (KJV) regarding those who are in the body of Christ, "And as many as walk according to this rule, peace be on them, and mercy, and upon the Israel of God."
Some folks might argue that Romans Chapters nine to eleven claim that all Jews will be saved. They quote Romans 11:26 (BBE) which says, "And so all Israel will get salvation: as it is said in the holy Writings, There will come out of Zion the One who makes free; by him wrongdoing will be taken away from Jacob:"
But look at the context of the verse and you'll see that Paul's writing about those of Israel who are faithful to the Lord verses those who were not. Likening them to olive tree branches, he said that it's possible to graft them back into the tree. Therefore, this Israel of God is all the faithful believers in the Lord down through the ages without regard to ancestry. Like wild olive branches, we gentiles who trust in Christ are grafted into the Israel of God tree.
There's so much more I could write but I'll save that for my next book called You Think You're Going to Heaven? It isn't a matter of genetics but of trust in God and his son which saves us from eternity in hell.
