Galatians 2:11-18 … when Peter came to Antioch, I had to oppose him publicly, speaking strongly against what he was doing, for it was very wrong. When he first arrived, he ate with the Gentile Christians, who don’t bother with circumcision. But afterward, when some Jewish friends of James came, Peter wouldn’t eat with the Gentiles anymore because he was afraid of what these legalists would say. Then the other Jewish Christians followed Peter’s hypocrisy, and even Barnabas was influenced to join them in their hypocrisy. When I saw that they were not following the truth of the Good News, I said to Peter in front of all the others, “Since you, a Jew by birth, have discarded the Jewish laws and are living like a Gentile, why are you trying to make these Gentiles obey the Jewish laws you abandoned? You and I are Jews by birth, not ‘sinners’ like the Gentiles. And yet we Jewish Christians know that we become right with God, not by doing what the law commands, but by faith in Jesus Christ. So we have believed in Christ Jesus, that we might be accepted by God because of our faith in Christ — and not because we have obeyed the law. For no one will ever be saved by obeying the law.” But what if we seek to be made right with God through faith in Christ and then find out that we are still sinners? Has Christ led us into sin? Of course not! Rather, I make myself guilty if I rebuild the old system I already tore down.
Galatians 3:1-9 O foolish Galatians! Who has bewitched you that you should not obey the truth, before whose eyes Jesus Christ was clearly portrayed among you as crucified. This only I want to learn from you: Did you receive the Spirit by the works of the law, or by the hearing of faith? Are you so foolish? Having begun in the Spirit, are you now being made perfect by the flesh? Have you suffered so many things in vain–if indeed it was in vain? Therefore He who supplies the Spirit to you and works miracles among you, does He do it by the works of the law, or by the hearing of faith?– just as Abraham “believed God, and it was accounted to him for righteousness.” Therefore know that only those who are of faith are sons of Abraham. And the Scripture, foreseeing that God would justify the Gentiles by faith, preached the gospel to Abraham beforehand, saying, “In you all the nations shall be blessed.” So then those who are of faith are blessed with believing Abraham.
Galatians 3:11-14 But that no one is justified by the law in the sight of God is evident, for “the just shall live by faith.” Yet the law is not of faith, but “the man who does them shall live by them.” Christ has redeemed us from the curse of the law, having become a curse for us (for it is written, “Cursed is everyone who hangs on a tree”), that the blessing of Abraham might come upon the Gentiles in Christ Jesus, that we might receive the promise of the Spirit through faith.
