Galatians 3:7-9, 26-29

Know therefore that they that are of faith, the same are sons of Abraham. And the scripture, foreseeing that God would justify the Gentiles by faith, preached the gospel beforehand unto Abraham, saying, In thee shall all the nations be blessed. So then they that are of faith are blessed with the faithful Abraham.

For ye are all sons of God, through faith, in Christ Jesus. For as many of you as were baptized into Christ did put on Christ. There can be neither Jew nor Greek, there can be neither bond nor free, there can be no male and female; for ye all are one man in Christ Jesus. And if ye are Christ’s, then are ye Abraham’s seed, heirs according to promise.
