God is particularly interested in what is going on within the heart of man. Specifically, He seeks for, and desires to find, TRUTH.
It is imperative that men speak the truth, for “he that speaketh the truth sheweth forth righteousness,” and his lip “shall be established for ever.”
The truth is more valuable than any earthly possession and it would be worth a man selling everything he owns just to possess the truth.
Most men would rather accept lies than to believe the truth. This bias against the truth has been present as far back as the garden of Eden.
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!
