snLet the water … be gathered to one place. In the beginning the water covered the whole earth; now the water was to be restricted to an area to form the ocean. The picture is one of the dry land as an island with the sea surrounding it. Again the sovereignty of God is revealed. Whereas the pagans saw the sea as a force to be reckoned with, God controls the boundaries of the sea. And in the judgment at the flood he will blur the boundaries so that chaos returns.
