What is David saying?

Psalm 33:6 & 9 “By the word of the Lord the heavens were made, their starry host by the breath if his mouth. For he spoke and it came to be; he commanded and it stood firm. David is stating the absolute wonder of Creation.  Our God is far beyond our comprehension.  You and I can do a lot of talking but we can never create out of nothing with words alone.  God did and in the most intricate and varied form.  When we get to heaven, I am positive we will be astonished and marvel at the home He has prepared for each of us.
