Every believer needs to understand this is a major point in our Christian life "Note that your Christian life and faith are not about you, they are about God and His purposes. Paul was not against Peter practising his Jewish traditions, what he was against was the hypocritical manner he was carrying it out and how it was destroying the fellowship of the brethren and the grace of God.
So let's stop hypocrisy, for it does much harm than God."
