5. For this they willingly are ignorant of. By one argument only he confutes the scoff of the ungodly, even by this, that the world once perished by a deluge of waters, when yet it consisted of waters. (Genesis 1:2.) And as the history of this was well known, he says that they willingly, or of their own accord, erred. For they who infer the perpetuity of the world from its present state, designedly close their eyes, so as not to see so clear a judgment of God. The world no doubt had its origin from waters, for Moses calls the chaos from which the earth emerged, waters; and further, it was sustained by waters; it yet pleased the Lord to use waters for the purpose of destroying it. It hence appears that the power of nature is not sufficient to sustain and preserve the world, but that on the contrary it contains the very element of its own ruin, whenever it may please God to destroy it.
For it ought always to be borne in mind, that the world stands through no other power than that of God's word, and that therefore inferior or secondary causes derive from him their power, and produce different effects as they are directed. Thus through water the world stood, but water could have done nothing of itself, but on the contrary obeyed God's word as an inferior agent or element. As soon then as it pleased God to destroy the earth, the same water obeyed in becoming a ruinous inundation. We now see how egregiously they err, who stop at naked elements, as though there was perpetuity in them, and their nature were not changeable according to the bidding of God.
By these few words the petulance of those is abundantly refuted, who arm themselves with physical reasons to fight against God. For the history of the deluge is an abundantly sufficient witness that the whole order of nature is governed by the sole power of God. (Genesis 7:17.)
