Peter admonished “newborn babes” in Christ to lay aside all hypocrisies. It is a natural battle that every babe in Christ must face. A new believer might have an inappropriate longing to please the one who led him to the Lord rather than giving the Lord preeminence. He might perform actions in hopes that his spiritual mentor will take notice. Eventually, this fault blossoms to the point where he begins to see problems in others while failing to realize the same problems exist in his own life. He might work hard to obey the strictest of commands while missing the overall desire of the Lord in his own life. Even as a babe in Christ, he must work to lay aside hypocrisy. Until he does, he will never grow into the mature believer the Lord wants him to be.
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.”
