The psalmist proclaims: “Behold, how good and how pleasant it is for brethren to dwell together in unity!” Unlike the unity of unbelievers and the heathen, the Lord rejoices in the righteous unity of His people. King David was someone who knew and experienced the difficulties of division. He spent a great deal of his life running from a king and those who were against him. Even in the beginning of his reign, the people were divided (2 Samuel 2:8-11). It was not until 7 1/2 years later that the people were united in David (2 Samuel 5:1-5). When the people dwelt in unity, David rejoiced. He likened it to the source of spiritual life for the nation of Israel, the priesthood (Psalm 133:2), and to the source of physical life in the dew of Hermon (Psalm 133:3). In other words, the right kind of unity gave life and hope to the nation!
We are to “fight the good fight of faith” (1 Timothy 6:12). This battle makes it imperative that we understand “we do not war after the flesh” (2 Corinthians 10:3). Unlike many of the cults, we do not use physical weaponry in our attempts to accomplish the will of God. No physical sword or weaponry can convert the lost to Christ; however, the Bible does instruct us to use the sword of the Spirit (Ephesians 6:17). In like manner, we do not have to resort to using physical weaponry to bring about our desired results during the spiritual battles. Instead, we flee to God's throne to find grace to help in time of need (Hebrews 4:16). We must insure that we do not carelessly allow ourselves to believe that the spiritual weapons are inferior to carnal weaponry. The Bible enforces this thought by reminding us that our weapons are “mighty through God to the pulling down of strong holds” (2 Corinthians 10:4).
Carnality becomes increasingly difficult to hide. Eventually, it clearly manifests itself in our daily actions. The carnality of the Corinthian believers showed itself in their relationship amongst their body of believers. They began to envy one another, eventually leading to strife and divisions amongst the group. When Paul learned of their failings, he knew carnality was at the root of the problem. Another action openly revealing the carnality of the people was their relentless desire to associate themselves with particular Bible teachers. They assumed an association with someone as well respected as Paul or Apollos would give them a spiritual boost among other believers. Considering their actions, Paul knew these believers were “yet carnal.”
