A careful study of our text helps to eliminate the controversy concerning confession. We have already seen that the Bible teaches that confession of sins is to be made only to God. Yet, our passage tells us to confess one to another. Yet, the Bible stipulates that the confession involves one's faults. The difference between sins and faults is quite simple. A fault is not a sin, but rather an area of weakness that could lead to sin. We do not profit from confessing our sins to each other or even to “religious leaders.” However, the Bible reveals the benefits derived from confessing that we covet the prayers of others to help overcome our areas of weakness. Perhaps, these brothers and sisters in Christ will fervently pray and even lend support and advice. This is why it is important to confess our sincere desire for their prayers. Unfortunately, misapplication of this passage to bodily healing has caused confusion. The context involves healing in areas of spiritual weaknesses, not simply a need for the body to be healed.
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!
