The world is driven by self-preservation and self-promotion. Individually, the natural man is guided by self-serving motives. This should not be true of saints.
Often the best way to expose one’s motives involves asking and answering the question “Why?” This question may resurface at the judgment seat of Christ.
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.”
