Which PROVES that Abram came from Adam & Eve = Gentiles/Nations from the Beginning = Eve the mother of all living
"Gentile did not come into existence until Abram the Hebrew entered into covenant with God and besides the covenant which no one else alive had with God, God sealed the covenant to first, be with the Hebrews of whom were the obedient descendants of Eber, and second, sealing the covenant to be specifically with Abram the Hebrew and sealed by circumcision. No other people were added to this covenant since it was only ONE man named Abram the Hebrew and each succeeding generation (Isaac, Jacob, etc.), expected the covenant as an inheritance when the promise of land had not been realized. The promises of making Abram's name great and to have descendants as the stars in the heavens as well as blessings were to take time (descendants) but also immediate (blessings.) God made clear Isaac was to be recipient of the covenant:
19 And God said, Sarah thy wife shall bear thee a son indeed; and
thou shalt call his name Isaac: and I will establish my covenant with him for an everlasting covenant, and with his seed after him.
Gen. 17:18–19.
Everything one needs to understand about this covenant with Abram the Hebrew and his descendants is found in Genesis 12, 15, and 17. One does not need to ADD to this covenant things that are not there. It shows that person who does this as ignorant and dishonest.
God changing Abram's name to Abraham also PROVES God's Plan of Salvation for the 'Nations/Goyim/ which the Hebrew nation came from'
No, it proves that God was keeping His promise by changing Abram's name to Abraham thus establishing that merely being a father was one thing but being a father of many establishes the beginning of God fulfilling his Promises and the first sign of God keeping His promises was to give Abraham and Sarah, his wife, a son whom God named "Isaac."
This is not hard to understand. If the Hebrew people came from Eber to Abraham and Abraham's wife was also his niece, then their offspring would be a Hebrew child (Isaac.) At this point in time "nations" may have been the Hebrew word "goy/goyim" but it did not mean Gentile as it is used today meaning "non-Hebrew" for the word is used to refer to Abraham and Sarah's offspring being in one child (Ishmael) half-Hebrew/half-Egyptian, as God says that Isaac was the seed of Promise and Ishmael was not (Rom. 9:7-13.) The inheritance then went to Jacob and NOT Esau although all of them were the seed of Abraham. You need to do a study of who took who as wife and follow the bloodlines that are listed in Scripture by God. Through both Ishmael and Jacob Abraham's descendants began to multiply however, despite this seed explosion the promises were inherited by Isaac, Jacob, and when he died to his twelve sons and when the promises were not totally realized the inheritance continued on to the descendants of the twelve sons of Jacob until we get to the time Jesus arrived and also decades and centuries after that. But at the time of Abraham and Sarah who were both Hebrew God saying that "nations" and "kings" will be "of them" refers to both the descendants of Ishmael and Isaac. "Nations" and "kings" came from both of Ishmaels' and Jacob's descendants, but "nations" did not mean "Gentile" because only an idiot would think "Gentiles" (non-Hebrew) would be born from two Hebrew parents and so on (meaning these offspring - at least where Jacob was concerned - married withing their families meaning more Hebrew children would be born. Ishmael married an Egyptian woman and also had other non-Hebrew wives which led to many "nations" and of whom many had been "kings." The word "nations" did not mean "Gentile" at the time but only as an identifier that one did not marry a fellow Hebrew and instead their children were of mixed heritage. "Nation" did not mean "Gentile or "non-Hebrew." Else, how do you explain the term "nation of Israel" who are Hebrew if you believe the tern "nation" means "non-Hebrew." Without going deeper into this subject I can tell you have not studied the genealogy in Genesis and Matthew and Luke. You haven't studied any of this and it shows.
God CREATED a separate nation unto Himself beginning with Abraham in order to FULFILL the Promise made to Adam/Eve and their descendants.
Anyone who argues against this argues against GOD's words of TRUTH and HIS Holy Nation.
"Holy Nation"? You mean the Jews? But I thought you said "nations" means "non-Hebrew Gentile"?
Your ignorance shows. You don't even know what you believe.
