Galatians
2:16/21
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.
21 I do not frustrate the grace of God: for if righteousness come by the law, then Christ is dead in vain.
3:6-11
6Even as Abraham believed God, and it was accounted to him for righteousness.
7Know ye therefore that they which are of faith, the same are the children of Abraham.
8And the scripture, foreseeing that God would justify the heathen through faith, preached before the gospel unto Abraham, saying, In thee shall all nations be blessed.
9So then they which be of faith are blessed with faithful Abraham.
10For as many as are of the works of the law are under the curse: for it is written, Cursed is every one that continueth not in all things which are written in the book of the law to do them.
11But that no man is justified by the law in the sight of God, it is evident: for, The just shall live by faith.
5:4-5
4 Christ is become of no effect unto you, whosoever of you are justified by the law; ye are fallen from grace.
5 For we through the Spirit wait for the hope of righteousness by faith.
