A basic definition of communication involves making things common. When we speak to others, we express what is in our minds and hearts making those thoughts common with others. The Bible warns the believer in Ephesians 4:29 to “Let no corrupt communication proceed out of your mouth, but that which is good to the use of edifying, that it may minister grace unto the hearers.” The words that come out of our mouths should edify or build up others, not demean and degrade them. They should be strengthened by what we say. Keep in mind that corrupt communications weaken the believer (1 Corinthians 15:33). This is why Christians are instructed to put off all “filthy communication” (Colossians 3:8).
The opening words of our passage express a desperate warning that is increasingly neglected today. The Devil has convinced many Christians that the content of their daily conversations has no bearing on their spiritual walk. The Bible, however, speaks to the contrary. In fact, the Lord sounded the warning “be not deceived.” Why? Because quite simply: evil communications corrupt good manners! Christians who desire to serve the Lord and please Him easily can be derailed by choosing to surround themselves with those using evil communications. It is very important to speak righteous things and surround ourselves with those who carry themselves in a Christlike manner.
Though peace may seem illusive, God instructs all believers to pursue after it. True inner peace is not something that one can afford to live without. The Bible says, “seek peace, and pursue it.” Peter reiterates this truth by saying, “seek peace, and ensue it” (1 Peter 3:11). Men should seek after peace; and when found, they should allow nothing to prevent them from fully seizing upon it. The Lord said, “therefore love the truth and peace” (Zechariah 8:19). Several New Testament verses repeat the importance of peace by admonishing the believer to follow after it (Romans 14:19; 2 Timothy 2:22; Hebrews 12:14). God certainly wants us to seek peace (1 Corinthians 7:15) and makes peace attainable. Yet, He demands that we pursue after His peace His way because any other peace is really no peace at all.
