God, who prepares His work for the ages, accomplishes it by the feeblest instruments. It is the method of His providence to produce great results from inconsiderable means. The law which prevades the kingdom of nature is discerned in the history of mankind. Truth makes silent progress, like the water that trickles behind the rocks, and loosens them from the mountain on which they rest. Suddenly the hidden operation is revealed, and a single day suffices to lay bare the work of years, if not of ages.
