Abraham was a descendant of Noah and the son of Terah (Gen. 11: 10-26). Promised to be the great progenitor of many nations (Gen. 17: 4). All nations are blessed through Abraham's seed, Jesus Christ (Gal. 3: 14, 16). Abraham is among the few privileged to have had special recognition with God (cp. Enoch and David, Gen. 5: 24; Acts 13: 22).
It is interesting to note what James said about Abraham, the father of the faithful: James 2:23 23 and the scripture was fulfilled which says, "Abraham believed God, and it was reckoned to him as righteousness"; and he was called the friend of God. (RSV)
Notice how James draws attention to the fact that Abraham was called the friend of God. The term "friend" is somewhat intimate and conveys a sense of closeness, trust, and sharing.
What is remarkable is that Abraham was termed the friend of God. The great, almighty, ever-present and all-powerful, all-knowing God was the one who made this statement. This was not Abraham's assessment of his relationship with God, nor how he thought about God. It was a statement that God made about Abraham.
The children of Israel were God's servants and were the offspring of Abraham, who was God's friend. Just consider for a moment how remarkable these words are, and what a remarkable relationship they describe! Consider that a limited, physical, mortal being would be thought of by the all-powerful, immortal, all-knowing, supreme God as His dearly beloved friend. Also consider that an imperfect man, made from the dust of the ground, would be viewed by the perfect Creator God composed of eternal spirit as one with whom He could have a warm, lasting and special friendship.
