Hebrews explains very nicely indeed why the Son of God is called the Word of God. Hebrews chapter 1 begins (American King James Version) "God, who at sundry times and in divers manners spoke in time past to the fathers by the prophets, Has in these last days spoken to us by his Son, whom he has appointed heir of all things, by whom also he made the worlds; Who being the brightness of his glory, and the express image of his person, and upholding all things by the word of his power, when he had by himself purged our sins, sat down on the right hand of the Majesty on high: Being made so much better than the angels, as he has by inheritance obtained a more excellent name than they."
He is the "express image of God" so not an inanimate image like a mountain reflected in a lake or a door reflected in a mirror - not an incidental reflection of God - not even a family likeness of God - but an image EXPRESSED by God - so like God spoke everything that Jesus is as a kind of autobiography of Himself - God expressed what He Himself is like by making His Son so much like Himself - yet human from the start and then eventually not just human or humanlike but real human flesh like us.
