I believe that the word of God is simply a reference to the expression of God. Jesus is himself the content of what God has spoken. To use colloquial terminology, he s the spittin image of his daddy. No one can see God, but you can see his glory. Trinitarians often use analogies to express their concept of God, such as the three points on a triangle, the three states of water or three interconnected circles.
Analogies can be helpful, if they accurately express the reality.
However, they can be very damaging if they do not. The only analogy that I am going to use is found in Scripture. This is beyond our comprehension. Scripture does not state that God is three points of a triangle, but it does state that Jesus is both the root and a branch. This we must affirm whether or not we can explain it.
