Galatians 2:13-16

13And the rest of the Jews also joined with him in this hypocrisy, so that even Barnabas was led astray with them by their hypocrisy.

14But 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?”

15We are Jews by birth and not Gentile sinners,

16yet 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.
