When God called Abraham out He called Him alone
BUT THOU, ISRAEL, ART MY SERVANT, JACOB WHOM I HAVE CHOSEN, THE SEED OF ABRAHAM MY FRIEND. Thou whom I have taken from the ends of the earth, and called thee from the chief men thereof, and said unto thee, and not cast thee away. Fear thou not; for I am with thee: be not dismayed; for I am thy God: I will strengthen thee; yea, I will help thee; yea, I will uphold thee with the right hand of my righteousness.
Behold, all they that were incensed against thee shall be ashamed and confounded: they shall be as nothing; and they that strive with thee shall perish. Thou shalt seek them, and shalt not find them, even them that contended with thee: they that war against thee shall be as nothing, and as a thing of nought. For I the Lord thy God will hold thy right hand, saying unto thee, Fear not; I will help thee. Fear Not, Thou Worm Jacob, and Ye Men of Israel; I Will Help Thee, Saith the Lord, and Thy Redeemer, the Holy One of Israel.” (Isaiah 41:8‑14; 43:10; 44:1-2; John 13:18)
Then God said in Genesis 18:18:
“Seeing that Abraham shall surely become a great and mighty nation, and All the Nations of the Earth Shall Be Blessed in Him?”
