Woe, to those who are in accordance with one's actions.

Galatians 2:16
Knowing that a man is not justified by the works of the law, but by the faith of Jesus Christ, even we have believed in Jesus Christ, that we might be justified by the faith of Christ, and not by the works of the law: for by the works of the law shall no flesh be justified.

I do not frustrate the grace of God: for if righteousness come by the law, then Christ is dead in vain.
