Not really Abraham is where the promise began regarding his descendants thoer acceptans was only because of the promise made to Abraham
“and I will bless them that bless thee, and curse him that curseth thee: and in thee shall all families of the earth be blessed.”
Genesis 12:3 KJV
“As for me, behold, my covenant is with thee, ( Abraham ) and thou shalt be a father of many nations. Neither shall thy name any more be called Abram, but thy name shall be Abraham; for a father of many nations have I made thee. And I will make thee exceeding fruitful, and I will make nations of thee, and kings shall come out of thee. And I will establish my covenant between me and thee and thy seed after thee in their generations for an everlasting covenant, to be a God unto thee, and to thy seed after thee.”
Genesis 17:4-7 KJV
“Look unto Abraham your father, and unto Sarah that bare you: for I called him alone, and blessed him, and increased him.”
Isaiah 51:2
Ect the Bible eventually builds up to this truth regarding aBrahams children of promise
“Now to Abraham and his seed were the promises made. He saith not, And to seeds, as of many; but as of one, And to thy seed, which is Christ.
For as many of you as have been baptized into Christ have put on Christ. And if ye be Christ's, then are ye Abraham's seed, and heirs according to the promise.”
Galatians 3:16, 27, 29 KJV
Abraham isn’t a cog in a wheel he’s the fether of our covenant he’s the man he the promise is made to the man of faith Abraham his faithfulness is why we have the promise
“And the scripture, foreseeing that God would justify the heathen through faith, preached before the gospel unto Abraham, saying, In thee shall all nations be blessed. So then they which be of faith are blessed with faithful Abraham.”
Galatians 3:8-9 KJV
you come to this eventually which is the promise
“And he said unto them, Go ye into all the world, and preach the gospel to every creature. He that believeth and is baptized shall be saved; but he that believeth not shall be damned.”
Mark 16:15-16 KJV
that came because Abraham was called by God to follow him in faith and he did in the kingdom abraham is a patriarch
