I had been taught that there was a vapor canopy over the earth before the Noahic Flood. But the words of Genesis Chapter One do not describe a vapor canopy. The creation details in Genesis unmistakably indicate that there is water above the stars.
We will accept the Genesis 1 creation story at face value to understand that there is a great sea above the universe.. Recognition of this will clarify Scriptures that commentators have found obscure (or “poetic”) from one end of the Bible to the other. This includes the statement that there will be no more sea in the new heavens and earth to come. Also we understand that God crosses this sea when He comes down from heaven and that we must quite literally (not only figuratively) cross a sea to go up to heaven . Then Scripture tells us the direction through the universe toward God’s heaven. It is situated above the celestial sea, which is frozen on the top (a crystal sea).
