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.
Man’s loyalty must be first and foremost directed toward the Lord; however, an aspect of one’s loyalty to the Lord also involves a certain loyalty toward man. At times, these loyalties might conflict. During those instances, each person should heed the words of Simon Peter when he admonished, “We ought to obey God rather than men” (Acts 5:29). When one’s loyalty to God does not conflict with any loyalty toward man, the Lord admonishes men to be loyal toward one another. When Moses placed his honour upon Joshua, he did so in order to encourage obedience, respect, and loyalty on the part of the people of God. In similar fashion, the Lord has crowned man with glory and honour (Psalm 8:5). As such, the Lord has naturally put within man a desire to be loyal toward the Lord and others.
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!
