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).
Most battles won have been won because of being equipped with the proper weaponry. Though the substance may be different in Christian warfare, the same theme prevails. No believer is nearly as successful in battle as he is when he dons “the whole armour of God” (Ephesians 6:11). This armour assists the believer as he seeks to stand “against the wiles of the devil” (Ephesians 6:11). This armour defends the loins with truth, the vital organs with righteousness (Ephesians 6:14), the head with salvation (Ephesians 6:17), and the entirety with faith (Ephesians 6:16). The same armour provides the offensive weaponry in the word of God and prayer (Ephesians 6:17-18). Notice that the spiritual weaponry lacks any emphasis upon the physical.
