Jesus acknowledged that the Jews were the descendants of Abraham, but that they weren’t the “children of Abraham” or the “children of God” anymore, but the “children of the devil”. Since Abraham is not their father, but the devil is, the promises that God gave to Abraham of those blessing Abrahams children being blessed does not apply to the Jews. They rejected Christ and are the children of the devil and not Abraham.
In John 8:37 Jesus said “I know you are Abraham’s descendants”.
in vs. 38, “If you were Abraham’s children,” said Jesus, “then you would[c] do what Abraham did.”
In vs 42, “If God were your Father, you would love me, for I have come here from God.
In vs 44, “You belong to your father, the devil, and you want to carry out your father’s desires.“
Anybody could be saved, but the promises to the “COA” weren’t to them because they weren’t apart of Abrahams nations.
Great. So we agree that there are spiritual covenants that don't apply to races, and we agree that the land covenant from 1499 to 586 BC was a national covenant that applied to a race. So as I said there are two kinds of covenants, and the only question left is whether there are national covenants today, which can be postponed to eschatology. So you can stop arguing.
The land convenant was to the “COA”. God now let’s only those who believe in Jesus be the “COA”, biology doesn’t matter anymore. Therefore it doesn’t belong to the children of the devil(Jews) anymore.
