First of all, the versions of the Bible I have seen use the term “chosen people” not race.
This statement in itself shows that God does has a specific people, as oppose to every man, woman child that ever lived.
The original Greek word that has been translated ‘people’ or ‘race’ in the interlinear Bible (from which all other English Bibles are based from) in 1 Peter 2:9 is the word genos (ghen’-os).
Strong’s Greek Dictionary defines it as:
“kin” (abstract or concrete, literal or figurative, individual or collective):–born, country(-man), diversity, generation, kind(-red), nation, offspring, stock.
It is the same word used in:
Acts 7:13
And at the second [time] Joseph was made known to his brethren; and Joseph’s
kindred was made known unto Pharaoh.
Acts 7:19
The same dealt subtilly with our
kindred, and evil entreated our fathers, so that they cast out their young children, to the end they might not live.
Acts 17:28
For in him we live, and move, and have our being; as certain also of your own poets have said, For we are also his
offspring.
Acts 17:29
Forasmuch then as we are the
offspring of God, we ought not to think that the Godhead is like unto gold, or silver, or stone, graven by art and man’s device.
Rev 22:16
I Jesus have sent mine angel to testify unto you these things in the churches. I am the root and the
offspring of David, [and] the bright and morning star.
Even if your translation uses race instead, it would be meant in a very broad sense and not in the anthropological sense.
I’ll agree with that. God’s family is spiritual in nature.
