[15] who are Jews by nature, and not sinners of the Gentiles, [16] Knowing that a man not justified by the works of the law, by the faith of Jesus Christ, even have believed in Jesus Christ, that we might be justified by the faith of Christ, and not by the works of the law: by the works of the law no flesh be justified. [17] But if, while we seek to be justified by Christ, ourselves also are found sinners, Christ the minister of sin? God forbid. [18] For if I build again which I destroyed, I make myself a transgressor. [19] For I through the law am dead to the law, that I might live unto God. [20] I am crucified with Christ: nevertheless I live; yet not I, but Christ liveth in and the life which now live in the flesh I live by the faith of the Son of God, who loved and gave himself for [21] not frustrate the grace of God: for if righteousness come by the law, then Christ is dead in vain.
