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.
During the Lord’s earthly ministry, His most malicious enemies were not common men or even the Roman government. His greatest enemies were the religious leaders charged with maintaining the spiritual purity of the people of God. How could those most religious create discord with the very One who gave them the dictates for the Jewish religion they claimed to defend? The answer is simple. It was envy! According to John 11:48, the religious leadership of Israel determined that they could not allow Jesus to continue teaching, preaching, and ministering to others. These leaders realized that all men would believe on Him causing the Romans to demote them. They would not allow this to happen. How far would they go to keep their place and nation? The Bible reveals that they would even cause the crucifixion of the innocent Son of God.
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!
