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.”
Our words should never be used by the Devil as weapons to destroy or discourage others. Any problem with our words reveals a problem with our heart: “out of the abundance of the heart the mouth speaketh” (Matthew 12:34). The mouth can exhibit good or bad and our actions reveal the heart of the problem when the Bible says, “out of the heart proceed evil thoughts, murders, adulteries, fornications, thefts, false witness, blasphemies” (Matthew 15:19). This is why our words are not always profitable to those who hear them. Yet, God admonishes us to “let no corrupt communication proceed out of” our mouth. Believers are instead encouraged to make sure their words are “good to the use of edifying.” The saint of God should speak words that God can use to build up other saints in the faith.
The knowledge of something wrong helps a spiritual person avoid such activity. On the surface, one might fail to distinguish much of a difference between the fruit of knowledge and charity in today’s passage. Both evidently build up the believer. Yet, a closer look reveals the major difference. The Bible says that knowledge “puffeth up.” The idea is that knowledge makes one feel superior and can offer a false strength. Knowledge seems to do the same work as charity, but knowledge without the charity serves as a façade. Charity, however, offers real growth and stability. Unlike knowledge, charity edifieth. Charity not only builds up the believer but also those who associate with that believer. The only way to be edified and the only way to edify others involves seeking the Lord for pure, unadulterated charity.
