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.
Our love for the words of God seems directly proportional to our willingness to contend for the truth. Those who love the law of God do not praise the wicked but instead contend with them. Contending against those who oppose God will not always be easy and will sometimes develop fearfulness from within. Yet, a believer who loves the Lord and His word will not idly sit by in the presence of wickedness without proclaiming the righteousness of God. Unfortunately, Christians are becoming increasingly fearful of speaking up in morally corrupt societies. Sometimes believers have allowed and even facilitated the wicked to spew forth their vile agenda and thoughts. However, those who truly love the Lord should be like the prophet Jeremiah who could not keep silent as he sensed the words of God like a fire shut up in his bones (Jeremiah 20:9)..
