Modern usage of the word conversation generally limits the definition to two people involved in a dialog. However, the Bible frequently uses the word conversation in a different sense. In fact, our passage reveals that a conversation can occur without words. Several other verses confirm connecting works to a man’s conversation (James 3:13; 1 Peter 2:12). The Bible’s use of conversation can involve something that others can observe (1 Peter 2:12; 1 Peter 3:2) and consider (Hebrews 13:7). Obviously, a man’s conversation is more complex than a simple discussion held between two or more persons. Scripturally speaking, our conversation reveals how we live our lives in front of others. Though this world would apply conversation only to what we say, God never intended for its usage to be limited to that single aspect.
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).
Our verbal communications involve the words that spring forth from our mouths. No doubt, the Lord considers these communications important and we should too. In today’s passage, the Lord gave some specific insights concerning His expectations of our communication. First, He wants our communication to be short and to the point – “let your communication be, Yea, yea; Nay, nay” (Matthew 5:37; see also Proverbs 10:19; Ecclesiastes 5:3, 7). Second, our word should be validated without the necessity of certifying it with vows, oaths, and swearing. In the context of the passage, the Lord Jesus forbade swearing “by heaven” (Matthew 5:34), “by the earth” (Matthew 5:35), or “by thy head” (Matthew 5:36). When we swear by these things, we put ourselves in danger of condemnation (James 5:12). Let your nay be nay and your yea be yea!
