Galatians 2:13-16

13And the rest of the Jews acted hypocritically along with him, so that even Barnabas was led astray by their hypocrisy.

14But when I saw that their conduct was not in step with the truth of the gospel, I said to Cephas before them all, "If you, though a Jew, live like a Gentile and not like a Jew, how can you force the Gentiles to live like Jews?"

15We ourselves are Jews by birth and not Gentile sinners;

16yet we know that a person is not justified by works of the law but through faith in Jesus Christ, so we also have believed in Christ Jesus, in order to be justified by faith in Christ and not by works of the law, because by works of the law no one will be justified.
