Believers are commanded to “Be careful for nothing.” Contextually, the word careful means to be care full or full of cares. That being said, this is one of the most disobeyed commands in all of scripture. In Matthew 6:25, the Lord warned His disciples against dwelling upon or worrying about what they would eat, or drink, or how they would be clothed. The Lord’s rebuke implies that not even the necessities of life should serve as a source of worry for God’s people. It is important to note that worry and faith are at opposite ends of the spectrum because they do not and cannot coexist within the believer’s life and walk. A believer who is “careful” for things cannot and will not simultaneously trust God’s faithful provision. When a believer worries rather than trusting in God’s provision and protection, the believer’s actions deem God incapable to accomplish the matter without the individual contributing his “carefulness.”
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.
