The enemies of God and of His people have always sought to conquer those weak in the faith by destroying their faith. Even now, false teachers seek to deceive the hearts of the simple – those who lack knowledge, understanding, and wisdom (Proverbs 8:5; Proverbs 9:4, 13). According to the scripture, these teachers do so “by good words and fair speeches.” It is not some raving, ranting lunatic that is most dangerous; it is the sweet talking, kind, loving, liar. In order to gain a following, a teacher must only appeal to others by sounding intelligent and offering “fair speeches” sprinkled with truth. If he can present things new to his audience, whether factual or not, the simple will become enamoured with his abilities and follow his teachings. This is why the Bible warns believers to have no fellowship with those who teach things contrary to the scripture. Any world religious leader who speaks softly and kindly yet fails to proclaim the true gospel probably lives more like a devil in private. The Bible calls these people wolves in sheep’s clothing.
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!
