No matter how deep the waters, to remain on the surface is to remain focused on God. God let it be known that even in the very beginning of the Bible, the waters are deep but He is on the surface. He does not sink nor does He become alarmed at even the greatest depths. He is always on top and He will keep us on top with Him in all things.
The earth was formless and empty, and darkness covered the deep waters. And the Spirit of God was hovering over the surface of the waters.
