Romans 3:22, 29-30

This righteousness of God comes through faith in Jesus Christ for all those [Jew or Gentile] who believe [and trust in Him and acknowledge Him as God’s Son]. There is no distinction, [1 Cor 12:13; Gal 3:28]

Or is God the God of Jews only? Is He not also the God of Gentiles [who were not given the Law]? Yes, of Gentiles also, since indeed it is one [and the same] God who will justify the circumcised by faith [which began with Abraham] and the uncircumcised through [their newly acquired] faith.
