Hold fast to the model of healthy or wholesome words, which thou hast heard from me. Many of us can remember building a model car or airplane. Once we had the model built we mounted it up high on a shelf for all to see. We must likewise have the Word of God as one of the primary models in our lives mounted high before our eyes. This model of the gospel must be built out of something that is called sound words .
Sound words is a medical term that means healthy or wholesome.
Sound words are healthy because they are true or are in accordance with what is factual concerning the Word of God. In our health craze society we must never forget the health that comes to us from knowing and living in accordance to sound doctrine. It is impossible for us to build a model of healthy words that we can frame before our eyes to unless we know the Word of God in truth or in accordance to fact. To know the Word of God in fact implies that we must do some serious study of the Word before we can truly know it in truth. Our knowledge of the Word of God must be so thorough that our teaching cannot be subject to the decay of time, error, or the opposition that comes from those that challenge our teaching.
