yet we know that a person is justified not by the works of the law but through faith in Jesus Christ. And we have come to believe in Christ Jesus, so that we might be justified by faith in Christ, and not by doing the works of the law, because no one will be justified by the works of the law.
References for Galatians 2:16
But if, in our effort to be justified in Christ, we ourselves have been found to be sinners, is Christ then a servant of sin? Certainly not!
But if I build up again the very things that I once tore down, then I demonstrate that I am a transgressor.
For through the law I died to the law, so that I might live to God. I have been crucified with Christ;
and it is no longer I who live, but it is Christ who lives in me. And the life I now live in the flesh I live by faith in the Son of God, who loved me and gave himself for me.
References for Galatians 2:20
I do not nullify the grace of God; for if justification comes through the law, then Christ died for nothing.
