Biblically speaking, a man’s name is equal to his character (Proverbs 22:1). This is why God’s character is often defined by His name. Faithful and true are two words that describe the very nature of God, but they are also names by which the Son of God will be called at His second advent (Revelation 19:11). Even the name Jesus was associated with the person and work of our Lord (Matthew 1:21). These names, and many more like them, are well known to believers, but few know that the Lord’s name is also said to be Jealous. Why? Because that is who He is! He is the One true and living God who demands man’s sole attention. Just as He is Faithful and True, God is also Jealous.
To communicate is to make something common. Communication can be accomplished in a variety of fashions. Communication can be between (1) an individual and his or her heart, (2) a person and the Lord, or (3) two or more people. According to Psalm 77:6, to commune with someone or something is to make “diligent search.” This thought may seem a bit foreign or odd today, but consider what takes place when people communicate. When someone communicates, words or thoughts are exchanged. Since words or thoughts originate in the heart (Matthew 12:34), communication is the searching and revealing of the heart. Communication discovers and makes known things of the heart to both participants.
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!
