Imagine the vulnerabilities of a watchman who refuses to keep his eyes open to every possible angle from which danger could arise. No doubt the enemy would scout the land observing the bad habits of the watchman. If the watchman fails to examine each point of entry, the enemy will attack from the unprotected angle. In like manner, believers are to walk circumspectly. The word circumspect means to look all around. Believers are to be sober and vigilant knowing that their enemy, the Devil, “walketh about, seeking whom he may devour” (1 Peter 5:8). God’s enemies always search for the weak spot where the hedge has been cut down or ignored. This is why there is no angle in the believer’s life that can be safely ignored.
Many Bible passages connect watchfulness and prayer. While preaching sounds the trumpet of alarm in the ears of men, prayer sounds the alarm in the ears of God. As a watchman, each believer has a responsibility to his brother or sister in Christ. While some believers are spiritually sleeping, unaware of their present danger, other believers ought to be standing upon the tower of watchfulness and calling upon the Lord. This was the point of Paul’s teaching in Ephesians 6:18 when he said, “Praying always with all prayer and supplication in the Spirit, and watching thereunto with all perseverance and supplication for all saints.”
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.
