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.“
Of course Jews aren't children of Abraham, because there is no such historical person. Just like there was no Moses. These are just made up stories and fictitious characters.
Our stories about Abraham and Moses developed as late as the Hellenistic period. The dating of the Hebrew Bible is a topic that remains unresolved. Many traditions and myths found among its pages are old indeed, but the text itself did not reach its final form until the Hellenistic period. If this claim is false it should not be hard to disprove. A single manuscript find could change everything, but I'm not holding my breath. Dr. Gad Barnea a historian at the University of Haifa, after examining every surviving Jewish document from the Persian period, recently stated that there is literally zero evidence for any knowledge of, and any familiarity with the Bible at that time. We may not know how far back the stories of Abraham, Moses, Joshua, David, Solomon, Esther, Daniel and other Bible heroes go. All we can say is that no one seems to have written anything down about them until after Alexander the Great and his Empire introduced Greek literature philosophy and culture to the near East.
"Scholars are divided on the existence of many of the great figures of Israel. I myself don’t believe there was a historical Abraham, Moses, or Joshua, for example (or if they did exist they were basically nothing like the figures described in the Hebrew Bible)." - Bart Ehrman, October 24, 2013
Preston, was there such a historical person as Abisha the Hyksos, a Semite who negotiated business with the house of Sesostris during the same period that Abraham was testified as negotiating the same business?
Was there such a historical person as the leader of the Hyksos departure from Avaris (Ramses) in ca. 1539 BC (called Moses by Manetho) where hundreds of thousands of Semites left Egypt for Canaan and, after a pharaoh power vacuum, Ahmose testified that a great tempest and a great blackout occurred?
