You are a Chosen Race ...
"But you are a chosen race, a royal priesthood, a holy nation, a people for God’s own possession" 1 Pet 2:9.
The language Peter here applies to new covenant believers is the same used of Israel in the Old Testament (Deut. 7:6-9) which does away with all specious arguments that "chosen" has different meaning for OT and NT believers.
The entire Bible declares that there is only ONE people of God. In contrast with what a whole generation of American believers have been taught, God did not make an "earthly people" when he created the ethnic Jews and another "heavenly people" when he created the the NT Church. This is an unbiblical bifurcation which no man was meant separate. Peter continues to quote from Deuteronomy, Isaiah, Exodus, and Malachi -- and employs the same language the Old Testament uses to describe Israel to describe the church. The Church and Israel are the "one new man" Paul speaks of in Ephesians chapter 2.
