Reread, or read The Bible all the way through, with prayer for The LORD to show you the things of truth in it. You will know that the Jew is still in existence, and the remnant will repent, believing in Jesus as their Messiah at the end of this age. You will also read about how the Jew, during the time of the gentiles, is temporarily blinded to Spiritual truth. I suggest you start reading your Bible all the way through, chapter, by chapter, daily. The Jew is still here, and is still God's chosen people. It is God who has kept them, and it is God who WILL save them.
It wasn't meant to be taken literally.
I agree with your comment .. thank you.
