Origination Someone once quipped that Abraham was a Gentile before He was a Jew! By that it was a reference to the literature that Abraham lived with his ancestors in Ur of the Chaldees. That was his native land. (Genesis 11:31, 15:7, Nehemiah 9:7)
Either because of economic necessity or looming military invasion by the Assyrians, the whole clan of Abraham's ancestors moved up north in the upper Fertile Crescent to Haran. This was in the land of the Hittites, and the city was an commercial center for caravans moving across the Tiger-Euphrates valleys. So it was said by one of the prophets, "Your mother was a Hittite." (Ezekiel 16:3-4)
Then Abraham moved down the western part of the Fertile Crescent into the land of the many Canaanite tribes, and became a traveling nomad there.
Now the Lord had said unto Abram, Get thee out of thy country, and from thy kindred, and from thy father's house, unto a land I will show you...and in thee shall all families of the earth be blessed. (Genesis 12:1-3)
Because of this origination, it would be proper to say that Abram (Abraham) was indeed a Gentile---according to the broad definition applied to non-Jews in the world. He was an ethnic as the Bible uses the term. And so there was no difference between the humanity of Abraham's family and any other people.
Promise to Man It was to this man that God spoke the promise of the Seed. And it was a promise that engulfed all of humanity, not just one race. Of course, Abraham needed a place to live, but the book of Hebrews explained that the real destination of living was a spiritual city, whose builder and maker was God.
By faith he sojourned in the land of promise, as in a strange land...for he looked for a city which has foundations whose builder and maker is God.
...They that say such things declare plainly that they seek a country. And truly, if they had been mindful of that country from whence they came out, they might have had opportunity to have returned.
But now they desire a better country, that is, a heavenly; wherefore God is not ashamed to be called their God, for He has prepared for them a city. (Hebrews 11:9-17)
Since This is So Since Abraham is of Gentile stock...since the promise of blessing was to the whole world...since the main goal is a "spiritual city" (spiritual realities)...would this not be sufficient reason, to not only interpret the Scriptures as a message for Equality of all Races, but be a basis to resolve the messy situation of Racism in the minds---and hearts---of people around the world? After all, is it not written:
For God so loved the world, that He gave... (John 3:16)
There is neither Jew nor Greek, there is neither bond or free, there is neither male nor female, for you are all one in Jesus Christ. (Galatians 3:28-29)
For He is our peace who has made both one, and has broken down the middle wall of partition between us. (Ephesians 2:14)
Could not the preaching and proclamation of the ancient promise to Abraham---without all the later Jewish legal trappings and rites and traditional customs---be a starting point, a rallying call, for racial reconciliation? For peace on earth and good will to men?
All Gentiles (ethnics), Abraham and everyone else, are the same flesh and blood people...whom God loves. (Acts 17:26)
