To communicate is to make something common. Communication can be accomplished in a variety of fashions. Communication can be between (1) an individual and his or her heart, (2) a person and the Lord, or (3) two or more people. According to Psalm 77:6, to commune with someone or something is to make “diligent search.” This thought may seem a bit foreign or odd today, but consider what takes place when people communicate. When someone communicates, words or thoughts are exchanged. Since words or thoughts originate in the heart (Matthew 12:34), communication is the searching and revealing of the heart. Communication discovers and makes known things of the heart to both participants.
Paul served as Timothy’s mentor. In fact, Paul referred to Timothy as his “son in the faith” (1 Timothy 1:2). As Timothy’s mentor, Paul gave Timothy truths with the intent that he would pass along those teachings to other believers. Though there are certainly variations of what should be taught, Paul laid out two foundational categories when he mentioned “words of faith and of good doctrine” (1 Timothy 4:6). Though specifics are given in the epistles of First and Second Timothy and Titus, every teaching should reflect the categories set forth by the apostle Paul. Even practical teaching ought to be based upon the words of God, as some teachings are good (2 Thessalonians 2:15), and some are bad (Matthew 15:9). Every teacher should teach with hopes of eventually learning from his students when they too become the teachers.
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!
