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).
Elkanah had two wives, one named Hannah and the other Peninnah. Peninnah had children, but Hannah remained barren. Peninnah used this opportunity of Hannah’s barren state to provoke her, hoping that she could trouble her rival. The Christian’s primary adversary is much different from Peninnah, but Satan’s goal and resolve is identical to this example. The adversary, the Devil (1 Peter 5:8), wants believers to live troubled, fretful, and defeated lives. If he can cause a believer to fret and to worry and to complain, he has a much greater chance of turning that believer’s heart against the Lord (Proverbs 19:3). The Devil knows that if he turns the heart, he might be able to cause that believer to curse the Lord (Isaiah 8:21). Satan uses worry as one of the foundational elements in his multipronged attack to bring about his greater objective. He wants to turn hearts against God! Those believers who struggle most with worry offer Satan the greatest chance of success
