Christians frequently find it difficult to consistently make their practice align with their position in Christ. The saints of God are positionally blameless in Christ, but practically, each believer must strive daily to “be blameless and harmless . . . in the midst of a crooked and perverse nation.” In this world, believers represent the Lord as sons of God. As such, they should “do all things without murmurings and disputings.” Why is this so very important? The importance points to the fact that believers are to “shine as lights in the world.” It is imperative that every believer strives daily to live a godly life and preserves a godly testimony in a world that has little to no knowledge of God (Matthew 5:16).
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!
