Most people do not understand or recognize that the law and grace are polar opposites. The law emphasizes man’s responsibility to God, while grace emphasizes God’s efforts toward man. The law’s purpose shows man his sin and points him to God for help (Romans 3:20). Additionally, the law condemns man and sheds light upon the fact that he has no hope. Interestingly, the first five books of the Bible (commonly called the books of the Law) make no reference to the word hope. Some might ask why? Because the law simply reveals that man has no hope apart from God. As such, the Lord Jesus brought in a “better hope . . . by the which we draw nigh unto God.” Any man who places his hope and trust in what he can do or must do for God has lost sight of what God must do for him.
A basic definition of communication involves making things common. When we speak to others, we express what is in our minds and hearts making those thoughts common with others. The Bible warns the believer in Ephesians 4:29 to “Let no corrupt communication proceed out of your mouth, but that which is good to the use of edifying, that it may minister grace unto the hearers.” The words that come out of our mouths should edify or build up others, not demean and degrade them. They should be strengthened by what we say. Keep in mind that corrupt communications weaken the believer (1 Corinthians 15:33). This is why Christians are instructed to put off all “filthy communication” (Colossians 3:8).
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!
