Paul speaks of how he opposed fellow apostle Peter, for his hypocritical and discouraging behaviour towards the young Gentile believers in Antioch. We too must ensure that our own conduct is not swayed by peer pressure by is always in step with the truth of the gospel.

Galatians 2:11–14

Paul Opposes Peter

11 But when Cephas came to Antioch, I opposed him to his face, because he stood condemned. 12 For before certain men came from James, he was eating with the Gentiles; but when they came he drew back and separated himself, fearing the circumcision party.¹ 13 And the rest of the Jews acted hypocritically along with him, so that even Barnabas was led astray by their hypocrisy. 14 But 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?”
