Throughout history, the countries with the smartest people has shifted from one ethnic group to another. Egyptian, Persian, greek, roman and chinese empires were all the most powerful empires in the world over the past 2000 years. They were mostly of different ethnicities and weren't white. Also the romans being white is just complete nonsense, the ancient roman historians described the romans having Mediterranean features in comparison to germans having western european features in contrast.
My point is that what determines the smartest ethnic groups are just circumstantial luck which allows the populace to take over neighboring countries, trade routes, and to acquire knowledge and advancements. Whites aren't just better than everybody else, contrary to what white supremacists would want you to believe.
And he said, Cursed be Canaan; a servant of servants shall he be unto his brethren. And he said, Blessed be the LORD God of Shem; and Canaan shall be his servant. God shall enlarge Japheth, and he shall dwell in the tents of Shem; and Canaan shall be his servant (Gen. 9:25-27).
For the gifts and calling of God are without repentance. For as ye in times past have not believed God, yet have now obtained mercy through their unbelief: even so have these also now not believed, that through your mercy they also may obtain mercy. For God hath concluded them all in unbelief, that he might have mercy upon all (Rom. 11:29-32).
God that made the world and all things therein, seeing that he is Lord of heaven and earth, dwelleth not in temples made with hands; neither is worshipped with men's hands, as though he needed any thing, seeing he giveth to all life, and breath, and all things; and hath made of one blood all nations of men for to dwell on all the face of the earth, and hath determined the times before appointed, and the bounds of their habitation; that they should seek the Lord, if haply they might feel after him, and find him, though he be not far from every one of us (Acts 17:24-27).
Sounds like there's potential for shifting of status and potential for retention of gifts both.
