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.
Sobriety is much more than simply a way of thinking; it is the scriptural approach to Christian living. The grace of God, through the Holy Ghost (John 16:13), teaches the believer the proper approach to living the Christian life. Grace teaches separation by stating that believers should deny “ungodliness and worldly lusts.” Yet, grace does not stop there. It also teaches a threefold approach to living life: “soberly, righteously, and godly.” Not only must a believer have a sober mind, he must also approach every aspect of his life with sobriety. He should pray with sobriety. He should read the scriptures with sobriety. He should witness with sobriety. Any contrary thing will cause the believer to suffer great loss.
