But after reading through all the responses I find there is not much iron and a great deal of clay which wont mix.
First, who is the elect of God?
Israel (or the Hebrews) for they are the people CHOSEN of God and given a salvation covenant. Three iof them.
6
For thou art an holy people unto the LORD thy God:
the LORD thy God hath chosen thee to be a special people unto himself, above all people that are upon the face of the earth.
7 The LORD did not set his love upon you, nor choose you, because ye were more in number than any people; for ye were the fewest of all people:
8
But because the LORD loved you, and because he would keep the oath which he had sworn unto your fathers, hath the LORD brought you out with a mighty hand, and redeemed you out of the house of bondmen, from the hand of Pharaoh king of Egypt.
9 Know therefore that the LORD thy God, he is God, the faithful God, which keepeth covenant and mercy with them that love him and keep his commandments to a thousand generations;
Dt 7:5–9.
There is no Scripture of God making any covenant with Gentiles. None.
But Gentiles have become saved and born-again and filled with the Holy Spirit of Promise (given to Israel.)
So, either God is saving non-Hebrew Gentiles without a covenant,
OR
Through Exile and scatterings Jews and Gentiles intermarriage or through rape, concumbinage, etc., Gentiles who believe themselves Gentile just might have Abraham's DNA in their family ancestry and since Scripture cannot be broken in Genesis 17:7 it says the covenant is with Abraham and his seed.
Even if you have a small dilution of Abraham's descendants in your blood as long as there is Abraham's DNA in your family you just might be his seed and the reason of your salvation.
