Since the garden in Eden, God has longed for fellowship with the very people He created (Genesis 3:8). In fact, one of the great reasons God desires for people to learn to communicate with others is so they can, in turn, understand how to better communicate with Him. Communication with God takes place in two major forms. Man communicates with God through prayer. Prayer can take place simply within one’s heart or verbally but can only be accomplished when a man conveys his thoughts or concerns to the Lord. God, on the other hand, communicates with man through the scriptures. Before Eve, communication existed between a man (Adam) and his God. Even in eternity, it appears that the greatest form of communication will exist between God and the redeemed.
The psalmist proclaims: “Behold, how good and how pleasant it is for brethren to dwell together in unity!” Unlike the unity of unbelievers and the heathen, the Lord rejoices in the righteous unity of His people. King David was someone who knew and experienced the difficulties of division. He spent a great deal of his life running from a king and those who were against him. Even in the beginning of his reign, the people were divided (2 Samuel 2:8-11). It was not until 7 1/2 years later that the people were united in David (2 Samuel 5:1-5). When the people dwelt in unity, David rejoiced. He likened it to the source of spiritual life for the nation of Israel, the priesthood (Psalm 133:2), and to the source of physical life in the dew of Hermon (Psalm 133:3). In other words, the right kind of unity gave life and hope to the nation!
People unite over various causes. Some of those causes are righteous, while others are not. Unity based upon a righteous cause pleases the Lord and leads to righteous acts. Unity based upon ungodly or carnal causes grieves the Lord and leads to the wickedness we find so prevalent in the world today. After the flood, the Lord commanded Noah and his family to “replenish the earth” (Genesis 9:1). They could not replenish the earth if they remained together so the Lord wanted Noah’s family to spread out across the earth. Yet, the people immediately began settling together and “Noah began to be an husbandman” (Genesis 9:20). This may seem insignificant, but it was only the precursor to the unified desire in Genesis 11:4 to build “a tower, whose top may reach unto heaven.” Noah’s disobedience led to further and greater disobedience and unity in a common wicked cause.
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!
