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.“
Always has been. Before Jesus came it was not determined by lineage either, but by whomsoever wills. For 2,000 years it was decentralized, then for 2,000 years it was focused on one nation, then for 2,000 years it was focused on the other nations, but it's never been closed to anyone. Jesus's lineage has many Gentiles who believed in the Messiah (seed of the woman) to come.
Since Jesus's first ministry led to a church of 5,000 Jews immediately, which increased to many tens of thousands of Torah-observant Jews in Jerusalem alone within years (Acts 21), it wasn't all Jews who were children of the devil, but it was whoever rejected God, as it always was. You're the one saying his promises don't change, take that literally.
It was, the promises in the Bible for Israel to inherit Canaan were specifically to the Jews descended from Abraham.
Yes, and after Jesus came, you could no longer be the “children of Abraham” by descent. They and every other people group were only the children of Abraham through believing in Jesus.
I responded to whether being a child of God was determined by human lineage: it isn't. Land promises are sometimes determined by lineage, with Jews and Gentiles alike: that's not relevant. Now, Luke points out that we're all children of God because Adam was begotten by God, but that's a different sense of child of God.
Similarly, child of Abraham has two senses, natural and spiritual. Children of Abraham by descent remain so regardless. Children of Abraham spiritually are those adopted by the God of Abraham, and once adopted they remain so regardless. You can be either or neither or both. The whole OT is to show that being a child of God (righteous) isn't dependent on human lineage (from God, Abraham, or anyone), but upon spiritual birth. Isaiah and Hosea call out physical Jews for not being of their father (spiritually).
One of the biggest things I had to lose from churchianity was the idea that the Jews were saved by works or lineage. By Hebrews 11 they and their predecessors were only saved by faith, same as we; those without faith were unsaved.
You are literally arguing with Jesus here. There is no “children of Abraham” by descent anymore
Jesus says in John 8, “I know that you are Abraham’s descendants…If you were Abraham’s children, then you would[c] do what Abraham did. As it is, you are looking for a way to kill me, a man who has told you the truth that I heard from God. Abraham did not do such things… If God were your Father, you would love me, for I have come here from God… You belong to your father, the devil, and you want to carry out your father’s desires. He was a murderer from the beginning, not holding to the truth, for there is no truth in him.
Jesus literally told the Jews they aren’t Abraham’s children or Gods but the devils. There are no two senses, you either believe in Jesus and are a “child of Abraham”, or aren’t one.
