Romans 3:9, 22

Well then, are we [Jews] better off than they? Not at all; for we have already charged that both Jews and Greeks (Gentiles) are under the control of sin and subject to its power.

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]
