Word plays vital role in communication. We make use of words in interacting with people whether at home or work. This makes it more important to carefully choose how we talk and the kinds of words we use. Our words must be weighed properly in the scale of Christian values and ethics. 
Words are very powerful. They can build and also tear apart. The words we speak can edify and can also demoralize the listeners. That is why Christians should be role models in the usage of words. Our words should always be with grace, seasoned with salt, that we may know how we must answer every one (See Colossians 4:6).
For Christians to be role models in word, the word of God must fill our minds. Since our thoughts produce the kinds of words we speak; it is important for us to renew our minds with God’s word always. As our thoughts align with God’s word, then the word that edifies listeners around us will flow accordingly.
There’s no better time than now for Christians to become role model in word. When we consider the root and cause of most devastating conflicts in the society, church, marriage and many other areas – it is always the misuse of the tongue.
The scripture made it clear in James 3:2 (Message translation). “We get it wrong nearly every time we open our mouths. If you could find someone whose speech was perfectly true, you’d have a perfect person, in perfect control of life.” 
It is very important for us to allow the Holy Spirit to guide our mind and mouths in the things we utter to people. We must also be careful of things we listen to from others. The kinds of words we repeatedly hear have a way of becoming the ones we may also likely to be uttering to others. And when we consider things we hear around us every day, they may not be helpful and spiritually healthy for our ears.
This is the reason we need to be selective in the kinds of words we permit for our ears. It is helpful if we can insist on hearing words that only glorify God – whether in reading or hearing.
Although, we may not be able to shut ourselves completely away from poisonous and infectious words around us – yet, we can consciously give ourselves to words that will bring positive and graceful words out of our mouth to others.
Henceforth, let us be a good Christian role model in our word. Let words that proceeds from us all the time be a source of blessing, healing, encouragement, uplifting and edification to the hearers.
Our words should be an example of what people must always hear from a believer. Such will make us a good example others can follow in word.
