Explain this extended metaphor created by Jonathan Edwards in this excerpt from his sermon "Sinners in the Hands of an Angry God." 'Tis true, that judgment against your evil works has not been executed hitherto; the floods of God's vengeance have been withheld; but your guilt in the meantime is constantly increasing, and you are every day treasuring up more wrath; the waters are continually rising and waxing more and more mighty; and there is nothing but the mere pleasure of God that holds the waters back that are unwilling to be stopped, and press hard to go forward; if God should only withdraw his hand from the floodgate, it would immediately fly open, and the fiery floods of the fierceness and wrath of God would rush forth with inconceivable fury, and would come upon you with omnipotent power; and if your strength were ten thousand times greater than it is, yea, ten thousand times greater than the strength of the stoutest, sturdiest devil in hell, it would be nothing to withstand or endure it.
