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!
Even since the Garden in Eden, God never intended for man to consider Him to be distant or unapproachable. In fact, the Bible repeatedly points out the opposite scenario. God's word proclaims that the Lord did not merely claim His followers as servants, but referred to them as His friends! He specifically referred to Abraham as the "friend of God" (2 Chronicles 20:7; James 2:23). He spoke to Moses “face to face, as a man speaketh unto his friend” (Exodus 33:11). These are not the actions of a God who desires separation from His creation. Though this intimate association with God seems remote and only expressed on a few occasions, John points out that we too can be God's friends (if we obey Him). This friendship must be based on mutual grounds because those who love the Lord are never lovers of the world. James 4:4 points out that “friendship of the world is enmity with God.” Though it appears that few people were called the friend of God, John chapter 15 suggests that this honour is much more prevalent than would appear. Christ told His followers, “Ye are my friends, if ye do whatsoever I command you” (John 15:14). Furthermore, Christ laid down His life for His friends (John 15:13).
