Galatians 2 - NLT

You and I are Jews by birth, not ‘sinners’ like the Gentiles. Yet we know that a person is made right with God by faith in Jesus Christ, not by obeying the law. And we have believed in Christ Jesus, so that we might be made right with God because of our faith in Christ, not because we have obeyed the law. For no one will ever be made right with God by obeying the law.
Galatians 2:15-16 faith law righteousness
My old self has been crucified with Christ. It is no longer I who live, but Christ lives in me. So I live in this earthly body by trusting in the Son of God, who loved me and gave himself for me.
Galatians 2:20 faith Savior life

I do not treat the grace of God as meaningless. For if keeping the law could make us right with God, then there was no need for Christ to die.
