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).
Any person who suggests that Christianity is simply an easy way to avoid the trials of life speaks as a fool or a liar. In actuality, the Christian life involves an ongoing, outward battle along with a constant inner struggle. Perhaps the greater of the two is the struggle which exists within a believer. Part of the Christian (called the new man) wants to do right, while the other part delights in doing wrong and following the old ways (the old man). Faith in God’s word and God’s plan is a primary means of assuring one’s spiritual success. Today’s passage focuses on the absolute necessity for personal faith within the life of a Christian. The book of Hebrews says, “without faith it is impossible to please him [God].” Hence, the Bible repeatedly states that unbelief displeases God. In fact, faith is so crucial to pleasing God that He devoted an entire Bible chapter pointing to the lives of those who exemplified faith. Since God spent the time, space, and effort to chronicle the faith of those of the past, He surely places no less emphasis on the faith of those living today.
