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.
The unity of believers is likened to a cord woven together. Like a threefold cord, unified believers are stronger and better able to endure the attacks from their enemies (Ecclesiastes 4:12). In Proverbs 6:16-19, the Lord gives a list of things He hates, one of which is when a man sows “discord among brethren.” What does it mean to sow “discord”? Perhaps the illustration given above sheds the necessary light for an answer. When believers are united, they are like multiple cords woven together. When someone sows discord, he attempts to undo or “discord” the threefold cord destroying the unity. Believers void of unity are weaker and more vulnerable to the attacks of the enemy.
People unite over various causes. Some of those causes are righteous, while others are not. Unity based upon a righteous cause pleases the Lord and leads to righteous acts. Unity based upon ungodly or carnal causes grieves the Lord and leads to the wickedness we find so prevalent in the world today. After the flood, the Lord commanded Noah and his family to “replenish the earth” (Genesis 9:1). They could not replenish the earth if they remained together so the Lord wanted Noah’s family to spread out across the earth. Yet, the people immediately began settling together and “Noah began to be an husbandman” (Genesis 9:20). This may seem insignificant, but it was only the precursor to the unified desire in Genesis 11:4 to build “a tower, whose top may reach unto heaven.” Noah’s disobedience led to further and greater disobedience and unity in a common wicked cause.
