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.
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!
The Devil was created perfect in every aspect (Ezekiel 28:15) with complete capacity to do right. Yet, he was also created with a free will to choose whether to do right or to do wrong. Sometime in the distant past, he chose to abide “not in the truth.” This conscious decision to depart from the truth caused him to become the “father” of lies. In one form or another, every lie traces back to the work of the Devil. As the enemy of God, Satan wants to deceive God’s creation into believing a lie so that rejecting the truth and remaining condemned in darkness (2 Corinthians 4:4) seems like the natural thing to do. Satan incorporates every deceptive means at his disposal. One of his main tactics is to convince people that there are many ways to heaven (good works, baptism, church membership, etc.) and many ways to know the truth (feelings, science, circumstances, etc.). Yet, the Bible emphatically proves that God is truth and His word is truth and only through God and His word are we assured of learning and knowing truth.
