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.
Christians frequently find it difficult to consistently make their practice align with their position in Christ. The saints of God are positionally blameless in Christ, but practically, each believer must strive daily to “be blameless and harmless . . . in the midst of a crooked and perverse nation.” In this world, believers represent the Lord as sons of God. As such, they should “do all things without murmurings and disputings.” Why is this so very important? The importance points to the fact that believers are to “shine as lights in the world.” It is imperative that every believer strives daily to live a godly life and preserves a godly testimony in a world that has little to no knowledge of God (Matthew 5:16).
The average believer when asked about his efforts to share the gospel may offer up several “reasons” why it is not feasible for him or her to tell others about their need for salvation. These reasons often seem spiritual in nature and are sometimes even accompanied by verses of scripture for support. However, the real truth is that believers who do not witness fail to do so because they are ashamed. Those believers who refuse to witness will be offended by this statement, but the apostle Paul confirms its validity. The reason Paul was “ready to preach the gospel” to those who were at Rome was because he was “not ashamed of the gospel of Christ.” Why was he not ashamed? Because he knew that it was “the power of God unto salvation.” Those who do not witness may offer excuses, but in reality they fail to believe in the power of God.
