Sobriety is much more than simply a way of thinking; it is the scriptural approach to Christian living. The grace of God, through the Holy Ghost (John 16:13), teaches the believer the proper approach to living the Christian life. Grace teaches separation by stating that believers should deny “ungodliness and worldly lusts.” Yet, grace does not stop there. It also teaches a threefold approach to living life: “soberly, righteously, and godly.” Not only must a believer have a sober mind, he must also approach every aspect of his life with sobriety. He should pray with sobriety. He should read the scriptures with sobriety. He should witness with sobriety. Any contrary thing will cause the believer to suffer great loss.
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!
