Paul’s description of the enemies of the cross suggests that they were controlled by their bellies. Paul may have meant something other than appetite when he used the word belly, but there can be no doubt that the idea is included. In Romans 16:18, Paul said that “they that are such serve not our Lord Jesus Christ, but their own belly.” In other words, those who are divisive and doctrinally unsound are led by their own lusts. The outcomes of their desires focus upon fulfilling their own lusts which Proverbs and Ecclesiastes reinforce. In Proverbs 16:26, the Bible says that man “laboureth for himself; for his mouth craveth it of him.” This is repeated in Ecclesiastes 6:7 where the Bible says, “All the labour of man is for his mouth, and yet the appetite is not filled.” These are just a few biblical examples of those ruled by appetite.
This world, though it consistently fails to recognize and know the Lord, should consistently recognize Christ's conversation through the life of the believer. Our conversation should always match, or become, the gospel of Christ and the new life that we have in Him. Our conversation should be holy because the Lord is holy (1 Peter 1:15). In 2 Peter 3:11, we learn that the dissolving of this world ought to cause us to walk “in all holy conversation and godliness.” In other words, our practical Christian life should resemble the change inside of us that took place at salvation. Others should see the Lord Jesus Christ in our actions and in our way of life.
