In John's Gospel we read, "In the beginning was the Word, and the Word was with God and the Word was God." He identifies this Word as Jesus.
Before words were written, all words were spoken. Words can also be thought, but, I would argue, genuine words must be spoken. Words represent ideas, which, of course, are thoughts. Words then are the oral representation of ideas.
Words are distinct from mere sounds. Words are organized sounds, sounds with ideas attached to them. Words are complex and somewhat mysterious. Even the simplest words call forth deep meaning.
So in the beginning, there was more than mere sound. In the beginning was the Word, something (or someone) deep and meaningful. There is purpose to this creation, because God spoke it into existence. This universe is mysterious, purposeful, safe, and dangerous.
There is depth to this existence, and God gives us life with which to explore it.
