Man does not change in order to be saved, but true salvation always brings about an evident change in the life of the new believer. Perhaps the change is less noticeable in some new believers and more noticeable in others; however, no change means no salvation. The change is not always an immediate outward change because it involves a change of the inward nature. A person who trusts Christ for salvation becomes a new creature (Galatians 6:15). It might be best to consider how this could be likened to a dog (Matthew 15:26-27) becoming a sheep (John 10:16). A new man now dwells within the new Christian to help combat and defeat the old sinful nature (Ephesians 4:22-24). Salvation is not merely the turning over of a new leaf; it is a new birth (John 3:3) where one is passed from spiritual death to spiritual life (John 5:24).
As already discussed, the word salvation is used throughout the word of God, but depending upon the context, the intended meaning varies. Failure to understand the different usages has led many to espouse some of the most egregious false doctrines. It is important to understand that the foundational meaning of the word salvation refers to deliverance. The vast majority of occurrences in the word of God actually refer to physical deliverance rather than a soul’s salvation. The word salvation can often be found within the context to describe the time when someone received deliverance from a specific trial or a threatening enemy. The most common usage today among believers relates to spiritual deliverance offered through the finished work of Jesus Christ.
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!
