Far too few believers consider the extent that God cares about what they do in, to, and through their bodies. The reality is that the believer is to glorify God in his body. Today’s passage instructs the saint of God to present his body to God as a living sacrifice. Amazingly, the Bible describes this spiritual sacrifice not as some great spiritual achievement but as a mere reasonable service (Romans 12:1). All true fellowship, consecration, and sanctification originate within one’s heart; however, it eventually works its way out to be visibly seen. A believer deceives himself if he claims to walk with God in sweet communion yet experiences no outward changes visible to mankind. A yielded Christian ensures that no part of his life is off limits to the Lord. He strives to ensure his life, including his body, is a testimony bringing glory to His Saviour.
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!
