Gal 2:11-13 Now when Peter had come to Antioch, I withstood him to his face, because he was to be blamed; 12 for before certain men came from James, he would eat with the Gentiles; but when they came, he withdrew and separated himself, fearing those who were of the circumcision. 13 And the rest of the Jews also played the hypocrite with him, so that even Barnabas was carried away with their hypocrisy.
The church in Antioch was the Apostle Paul’s base of operation for ministry. Antioch was his home church. It was also the place where the name Christian originated. Peter came to visit Paul and see the church. When Peter first arrived, he mingled with the Gentiles and enjoyed their fellowship. Yet another group of Jewish believers arrived in Antioch and Peter quickly separated himself from the Gentiles. Peter was worried about what they might say. He did not want to be looked down upon by his orthodox brethren. When Paul observed the change in Peter's behavior he reproved him. Peter had fallen prey to a common temptation we all face, "the fear of man."
One minute we are unashamed of what we believe and the convictions we have, but the next minute we conceal it lest we be identified and looked down upon. The Bible says, "the fear of man brings a snare, but whoever trusts in the Lord shall be safe." Proverbs 29:25.
Do not be afraid to be who you are. Rather than fear man, fear God. Whether you at the office, or on your campus, or amidst your relatives; be the light of the world. Choose to identify with Jesus even if it means people may not be accepting of you. Your an ambassador, a child of the King of Kings, a follower of Jesus; and that is nothing to be ashamed of.
