Galatians 2:4-5

2:4 Now this matter arose because of the false brothers with false pretenses who slipped in unnoticed to spy on our freedom that we have in Christ Jesus, to make us slaves. 2:5 But we did not surrender to them even for a moment, in order that the truth of the gospel would remain with you.

Galatians 2:12-16

2:12 Until certain people came from James, he had been eating with the Gentiles. But when they arrived, he stopped doing this and separated himself because he was afraid of those who were pro-circumcision. 2:13 And the rest of the Jews also joined with him in this hypocrisy, so that even Barnabas was led astray with them by their hypocrisy. 2:14 But when I saw that they were not behaving consistently with the truth of the gospel, I said to Cephas in front of them all, “If you, although you are a Jew, live like a Gentile and not like a Jew, how can you try to force the Gentiles to live like Jews?”

Jews and Gentiles are Justified by Faith

2:15 We are Jews by birth and not Gentile sinners, 2:16 yet we know that no one is justified by the works of the law but by the faithfulness of Jesus Christ. And we have come to believe in Christ Jesus, so that we may be justified by the faithfulness of Christ and not by the works of the law, because by the works of the law no one will be justified.

Galatians 2:21

2:21 I do not set aside God’s grace, because if righteousness could come through the law, then Christ died for nothing!
