An intelligent plain man, untaught in the truths of Christianity, coming upon this text, would likely conclude that John meant to teach that it is the nature of God to speak, to communicate His thoughts to others. And he would be right. A word is a medium by which thoughts are expressed, and the application of term to the Eternal Son leads us to believe that self-expression is inherent in the Godhead, that God is forever seeking to speak Himself out to His creation. The whole Bible supports the idea. God is speaking. Not God spoke, but God is speaking. He is by His nature continuously articulate. He fills the world with His speaking Voice.
One of the great realities with which we have to deal is the Voice of God in His world. The briefest and only satisfying cosmogony is this: "He spake and it was done." The why of natural law is the living Voice of God immanent in His creation. And this word of God which brought all worlds into being cannot be understood to mean the Bible, for it is not a written or printed word at all, but the expression of the will of God spoken into the structure of all things. This word of God is the breath of God filling the world with living potentiality. The Voice of God is the most powerful force in nature, indeed the only force in nature, for all energy is here only because the power-filled Word is being spoken.
The Bible is the written word of God, and because it is written it is confined and limited by the necessities of ink and paper and leather. The Voice of God, however, is alive and free as the sovereign God is free. "The words that I speak unto you, they are spirit, and they are life." The life is in the speaking words. God's word in the Bible can have power only because it corresponds to God's word in the universe. It is the present Voice which makes the written Word all-powerful. Otherwise it would lie locked in slumber within the covers of a book.
