Peter knew that the Gentiles were no longer to be considered unclean (Acts 10:9-16), and he demonstrated this by eating with them. However, when some prominent Jews arrived, Peter “withdrew and separated himself, fearing them which were of the circumcision.” He knew better but allowed fear to cause him to rebel against the clear teachings of the Lord. As such, Peter “was to be blamed” (Galatians 2:11), and Paul had to rebuke him. It is one thing for a man to sin against the Lord through ignorance, but Peter knowingly, purposely, and openly violated God’s word. In like manner, believers today must bear the blame and the shame when they sin against the clear teachings of scripture.
When one side defeats another in battle, to the victor goes the spoils. This means that the victor enters the camp of the defeated and takes its valuable possessions (including women, children, material goods, etc.). With this truth in mind, the apostle Paul warned the believers at Colosse to be on guard, knowing that men would seek to spoil them through philosophy and vain deceit. In other words, accepting the philosophies of men, or false doctrines, is likened to losing a battle and allowing the enemy to rob the believer of his most valuable possessions. It is important to understand that although a believer can never lose his salvation, he can be robbed of his stability, growth, peace, and joy.
