There is an old saying, something to the effect: If a tree falls in the forest and no one is there to hear the crash, does it make any sound?
Of course, we may be sure that it does. But the point is, I think, that if no one hears it, it doesn’t matter. So too with God. It is a staggering thought to contemplate, truly incomprehensible and positively frightening, but Jehovah has always existed and before he became the Creator he was alone – forever. Of course, we cannot comprehend timelessness, but it was not as though God were twiddling his thumbs for an eternity. But, at some point Jehovah determined to become a Creator. And we should all be glad at that happy decision. So, then, his very first creation is called the Word, the Firstborn of all creation. And with the birth of the only-begotten son of God the Scriptures tell us that God saw fit to have all wisdom and knowledge and power dwell in his son, who later became Christ Jesus.This is what the Scriptures teach and it is what Jehovah's Witnesses believe.
The point is, God has always been wise, in fact the scripture says of God, 'you alone are wise.' But with the coming into existence of the Firstborn, at that point God’s wisdom became manifest. And as more creatures came into existence through the powers and wisdom given to the Word, they could then appreciate the wisdom of God, which was first expressed in the beginning of creation in the Word.
That is why the Proverbs personifies the quality of wisdom because, before God created so much as an atom or molecule, he made a heavenly person, a son, to be in his exact image and representation.
Again, that is what the Bible teaches and it is what Jehovah's Witnesses believe.
