Now when Peter had come to Antioch, I withstood him to his face, because he was to be blamed; 12 for before certain men came from James, he would eat with the Gentiles; but when they came, he withdrew and separated himself, fearing those who were of the circumcision. 13 And the rest of the Jews also played the hypocrite with him, so that even Barnabas was carried away with their hypocrisy.
14 But when I saw that they were not straightforward about the truth of the gospel, I said to Peter before them all, “If you, being a Jew, live in the manner of Gentiles and not as the Jews, why do you compel Gentiles to live as Jews? 15 We who are Jews by nature, and not sinners of the Gentiles, 16 knowing that a man is not justified by the works of the law but by faith in Jesus Christ, even we have believed in Christ Jesus, that we might be justified by faith in Christ and not by the works of the law; for by the works of the law no flesh shall be justified.
17 “But if, while we seek to be justified by Christ, we ourselves also are found sinners, is Christ therefore a minister of sin? Certainly not! 18 For if I build again those things which I destroyed, I make myself a transgressor. 19 For I through the law died to the law that I might live to God. 20 I have been crucified with Christ; it is no longer I who live, but Christ lives in me; and the life which I now live in the flesh I live by faith in the Son of God, who loved me and gave Himself for me. 21 I do not set aside the grace of God; for if righteousness comes through the law, then Christ died in vain.” —Galatians 2:11-21.
Paul insisted that salvation could only come by faith in Christ Jesus. In dying to justification by the works of the law, and living by faith in the Son of God, Paul taught that Christians should reflect the fact that salvation is by grace and not by the works of the law. The death of Christ and His risen life are fundamental to this. The false teaching of salvation by works empties the cross of Christ of its real meaning and purpose. [The Bible Panorama.]
