——>The new covenant was made with believing Israel and Judah.
And then there was this...
Matthew 21:Therefore say I unto you, The kingdom of God shall be taken from you, and given to a nation bringing forth the fruits thereof.
Acts 13:46
Then Paul and Barnabas answered them boldly: “It was necessary to speak the word of God to you first. But since you reject it and do not consider yourselves worthy of eternal life, we now turn to the Gentiles.
Acts 28:28
Be advised, therefore, that God’s salvation has been sent to the Gentiles, and they will listen!”
Israel, AS A NATION, is finished. They rejected Christ, and there is no coming back from that. God cancelled their favored status ticket. However, salvation is open to all INDIVIDUALLY, who call on the name of Christ as their Savior.
Galatians 3:28-29
There is neither Jew nor Greek, slave nor free, male nor female, for you are all one in Christ Jesus. / And if you belong to Christ, then you are Abraham’s seed and heirs according to the promise.
Acts 18:5-6
When Silas and Timothy came from Macedonia, Paul devoted himself exclusively to preaching, testifying to the Jews that Jesus was the Messiah. But when they opposed Paul and became abusive, he shook out his clothes in protest and said to them, “Your blood be on your own heads! I am innocent of it. From now on I will go to the Gentiles.”
That boldface line indicates there is no special dispensation for Jews who reject Christ. No special salvation by virtue of their DNA.
