Jesus said,

John 6:63
It is the spirit that quickeneth; the flesh profiteth nothing: the words that I speak unto you, they are spirit, and they are life.

What are the words we are speaking?  Are they spirit, that is from the Spirit? Are they life, do they contain life? Words are containers, they are filled with something. "Death and life are in the power of the tongue:" Prov. 18:21. 
Words are creative, they create the reality or the world we live in. What we fill our words with will be reproduced in our days.

By way of illustration, let me share a story. I have a a Pastor friend who lives in a house in the country, across the road was a piece of property that  he and his family wanted so they could build a new home. He began to speak about it to others, not necessarily "claiming it" but speaking his desire, being thankful and looking for an opportunity. To make a long story short, they purchased the land and are making plans to build. He had a vision, a thought , a dream, he thought about it, talked about it, pursued it and the "mountain is moving". He is creating "his world". You and I are doing the same kind of thing all the time in a myriad of different ways. The question is what are we building? What is in our words? What are we filling our world with?

Words are the expressions of thought. What we think about deeply and often will eventually become what we say and do. 

Psalms 19:14
Let the words of my mouth, and the meditation of my heart, be acceptable in thy sight, O Lord, my strength, and my redeemer.

Lets get our thoughts and words from the same source Jesus did, the Spirit, and lets fill our words with life like He did... It's possible... Words that are spirit and life are words that are acceptable in the sight of our God. Acceptable thoughts and acceptable words will produce an acceptable life.
