A Four Letter Word

John 1:1 ESV

In the beginning was the Word, and the Word was with God, and the Word was God.

What we can know about God is contained in His Word. He is the word. 

Our understanding and expression of creation is accomplished through the use of symbols which attempt to package our reality in abstract terms. We interact with the world through our senses, but we experience the world in the abstract. This is most often done in the form of words and language. It provides the tools for thinking in the abstract and to communicate with others. Other forms of communication include art and music. Words can be elevated to art. This is expression, which is an attribute of God and part of His image that marks mankind. 

That is why He reveals Himself through the word, and through the word we are revealed. The word is our beginning and can mold us in His image in the end.
