Galatians 2:15-16

15[I went on to say] “We are Jews by birth and not sinners from among the Gentiles;

16yet we know that a man is not justified [and placed in right standing with God] by works of the Law, but [only] through faith in [God’s beloved Son,] Christ Jesus. And even we [as Jews] have believed in Christ Jesus, so that we may be justified by faith in Christ and not by works of the Law. By observing the Law no one will ever be justified [declared free of the guilt of sin and its penalty].
