God exhibits the perfect standard of righteousness through His character and work. Any person desiring to know the right way to do something should look to the Lord for his example. The Bible says that God gives liberally to man. If one needs wisdom, all he need do is to ask the Lord for wisdom and God promises to give man the wisdom and to give it in a liberal fashion. Fortunately, this promise is not in any way restricted exclusively to wisdom but also includes the manner in which God gives to man in other areas of life. Look no further than Calvary for proof of this truth. At Calvary, God gave liberally in the sacrifice of His Son. As a result of that sacrifice, God promises that whosoever will can come to God for salvation. Since God gives so liberally to man, how should man give to God?
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!
