A believer should be controlled only by the Lord. At no point should a man be controlled by the cravings of his body, even that of his appetite. No doubt, Paul’s words above covered a much broader scope than simply a man’s appetite, but he too understood the need to control one’s cravings. The Bible records several instances where Paul was hungry and had nothing to eat (2 Corinthians 11:27). Solomon warned his son about the need for controlling one’s appetite when seated before rulers at a meal. He admonished, “When thou sittest to eat with a ruler, consider diligently what is before thee: And put a knife to thy throat, if thou be a man given to appetite” (Proverbs 23:1-2).
God is as equally concerned with what we do as to how we do it. It is not only important that we have the right kind of conversation, but that our conversation be based on “simplicity and godly sincerity.” In other words, our conversation should be genuine and never extravagant. People behave for different reasons. Sometimes those reasons are godly, yet at other times they reflect ungodliness. Anyone can feign a good conversation for a short period; however, only with the Lord's help can one's motives consistently match his actions. Paul not only sought to have his conversation right before the Lord, but also desired a genuine change of heart to bring forth the proper conversation.
The Bible teaches us that “if any man be in Christ, he is a new creature” (2 Corinthians 5:17). Following salvation, a man's life should display visible changes as he seeks to put off his former conversation. According to scripture, that former conversation fulfilled “the desires of the flesh and of the mind” (Ephesians 2:3). By the grace of God, change is possible because every believer has been redeemed from his “vain conversation” (1 Peter 1:18). The apostle Paul is a great example. Before meeting the Lord on the road to Damascus, Paul's conversation or lifestyle involved mercilessly persecuting the church (Galatians 1:13). In his new life with Christ, he immediately began preaching the very faith he once destroyed (Galatians 1:23). When a person truly places his faith for salvation in the finished work of Christ, his conversation will change accordingly.
