The traditions of men produce lives lived in vain. According to scripture, the word conversation means much more than merely words being spoken from one person to another. The context shows that the word refers to the way in which a person lives his life (2 Corinthians 1:12; 1 Peter 3:1). As such, those who build their lives upon the traditions of men may work very hard and be even deemed faithful. Yet, this life is all for naught because their lives are built upon vanity. Sadly, some of the most faithful followers of religion are those who are promoting the traditions of men from which they will gain no eternal benefits. The only conversation that proves fruitful in eternity is the one built upon the commandments of God.
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.
