Actually in the old testament, Jewishs (Israel) people was the elected ones, and others races around their nations was enemies because of their idolatry and blasphemy. But, God was accepting people of others nations if they were following the Israel Cult. After in the the new testament, When jesus-Christ came as savior of the world and the mankind, to safe the entire humanity who is believing in him.
So, i think that God is taking human as a human, then the color or language speaking dont change anything in the redemption of them. But, from the bible writing, Idolatry of others religions is not permit and god seem really sensitive about this.
PS : Would like to be corrected if im wrong plz
