Galatians 2:11-14.  When he encountered Peter’s hypocrisy, Paul could have done the same thing Peter did, claiming Peter’s authority. That would have been the easy thing to do. But there was a lot at stake here. It was not just the traditions of men, whether Jewish or Gentile. The truth of the gospel was at stake. So Paul publically opposed Peter.
Paul was being a good friend here. All of us are able to make wrong choices which deny what we profess. If that happens, may God give us a friend like Paul, who cares enough to confront us.
This story is included in Galatians because the Galatian believers were being threatened with the same false teaching that the “certain men from James” had with them when they visited Antioch. The Galatians would have to make the same choice that Peter did. They would have to repent and get back in step with the gospel that they profess.
This story suggests a few principles for living like a Christian in any age.

When you and I gave our lives to Jesus Christ, we accepted the gospel of the kingdom, and agreed to live by its principles.
Are we still living by those principles? Have we taken on any new habits and practices since then?

LORD, help us to examine ourselves to see if we are still living by the gospel that we accepted when we first came to you.
