Jesus Christ is the Eternal Word. He, and He alone, is the source of new life to you.For you to have new life, he must be communicated to you. (Experiencing the Depths of Jesus Christ, Jeanne Guyon, Chapter 14 Silence.)Here I see a strong basis for practicing silence before God. I have not really thought about this particular significance of Jesus being called the Word in John 1. Perhaps above all things, Jesus needs to be heard to be received.
Hearing has a strong place in the Bible. The creation is spoken into existence. Could it be that such communication from God was meant most of all to be heard? Psalm 19 says, "The heavens declare the glory of God!"
The Shema of Israel begins with "Hear, O Israel!" The word is also translated "obey." Is it possible we find ourselves trying to obey without first hearing? Perhaps this is what Jesus was driving at when he said, "Why do you call me 'Lord,' and do not do what I command?" Perhaps the first command is listening more than professing.

SILENCE THAT HEARS
Here is how to acquire this habit of silence. First of all, forget yourself.Perhaps I will lose some people at this point. The idea that any person could actually do anything to effect or further their own salvation is unthinkable to some people. If it is the idea that silence itself has such an effect, I would agree wholeheartedly. But to say that God will deliver us apart from our cooperation is to deny the one who calls out, "Repent, for the kingdom of heaven is at hand!"
Silence that hears is first a form of self-denial. It is not a form of self-abuse! It is laying aside the voice that chatters incessantly about me. It begins when my attention shifts. That shift must first be away from myself if I am to truly hear.
This is not surprising. Any person who has practiced silence for the sake of careful listening knows that one of the greatest barriers to hearing is planning a reply even as someone is speaking to you. With this kind of anticipation is the judgment that you already understand what the person is saying before they have said it. Not only does this leave out important details and information, it signals to the person that you do not really care what they are saying, only what you will be replying.
Perhaps this is how we are with God. Silence can help us to escape our tendency to answer God before we know what he is saying. Perhaps we may find ourselves able to hear him out instead of putting words into his mouth.
WAIT ON GOD
Second, listen attentively to God.

When we can forget ourselves for a while, we find he is not far from us. What keeps God distant is our continuous plague of self-absorption. It is not enough to remove attention from ourselves, though. We must wait on God.
The mind is a slippery thing. You think you have a hold on it and it slides away into another stream of thoughts and anxieties. The streams of the mind are formed, like trenches dug and used. If the prevailing stream is of what I want, the mind continually slips down that trench. The good news is that this stream is not very deep or strong. There are much greater torrents that can capture the mind.
THE GOD I WANT TO HEAR

At the heart of silence is a God who wants to be heard and a God whom I want to hear. Without this knowledge firmly planted in my belief, silence will only be a strain and an exercise rather than a doorway to a life-giving, deeply loving relationship. Without this knowledge the Eternal Word will remain a nice idea rather than the source of life.
