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.”
Unity only comes from and through the Lord Jesus Christ, but once it comes, the saints of God must endeavour to keep that unity. One of the reasons why people find unity so elusive is because it requires sacrifice from all those who would enjoy its benefits. Only saints who exercise “lowliness and meekness, with longsuffering” will experience unity. No two believers who are using the minds that God gave them will believe every minute detail alike, yet they can enjoy sweet unity and fellowship in the Lord. Obviously, there are times and reasons for believers to divide, but there are also times for believers to forbear “one another in love” and endeavour to keep the unity. This unity works by love and can only be bonded through peace.
