Galatians 2:17-20

But if, while we seek to be justified in Christ [by faith], we ourselves are found to be sinners, does that make Christ an advocate or promoter of our sin? Certainly not! For if I [or anyone else should] rebuild [through word or by practice] what I once tore down [the belief that observing the Law is essential for salvation], I prove myself to be a transgressor. For through the Law I died to the Law and its demands on me [because salvation is provided through the death and resurrection of Christ], so that I might [from now on] live to God. I have been crucified with Christ [that is, in Him I have shared His crucifixion]; it is no longer I who live, but Christ lives in me. The life I now live in the body I live by faith [by adhering to, relying on, and completely trusting] in the Son of God, who loved me and gave Himself up for me.
