He was with God in the beginning.
The personal pronoun tells us that the 'word' is a person not a personification. He was with God and he was God. And he was there at the beginning. We can have no truck with the JW's notion that Jesus was a created being. At the very start we have here evidence of the plurality of personage in God. I don't understand the Trinity. I could not explain it. But then if I could I would be like God. There are mysteries in the Bible that we will only understand in heaven. Sometimes we just have to say, "I don't understand, but I believe."
