It was in God’s heart since the Exodus to wipe out that “people,” and make a new people from His Son Jesus Christ:
Then the Lord said to Moses, “I have seen this people, and behold, they are an obstinate people. So now leave Me alone, that My anger may burn against them and that I may destroy them; and I will make of you a great nation.” Exodus 32:9-10
Only those in Jesus Christ are the Chosen People.
We are Mount Zion and the Heavenly Jerusalem (Hebrews 12:22).
A nation or religion that refuses to worship Jesus Christ are the anti-Christ:
By this you know the Spirit of God: every spirit that confesses that Jesus Christ has come in the flesh is from God; and every spirit that does not confess Jesus is not from God; this is the spirit of the antichrist, which you have heard is coming, and now it is already in the world. 1 John 4:2-3
