Galatians 3:28-29

There is [now no distinction in regard to salvation] neither Jew nor Greek, there is neither slave nor free, there is neither male nor female; for you [who believe] are all one in Christ Jesus [no one can claim a spiritual superiority]. [Rom 3:22; 1 Cor 12:13] And if you belong to Christ [if you are in Him], then you are Abraham’s descendants, and [spiritual] heirs according to [God’s] promise.
