John Chrysostom

"But we have this treasure in earthen vessels, that the exceeding greatness of the power may be of God, and not from ourselves."

For seeing he had spoken many and great things of the unspeakable glory, lest any should say, 'And how enjoying so great a glory remain we in a mortal body?' he saith, that this very thing is indeed the chiefest marvel and a very great example of the power of God, that an earthen vessel hath been enabled to bear so great a brightness and to keep so high a treasure. And therefore as admiring this, he said, "That the exceeding greatness of the power may be of God, and not from ourselves;" again alluding to those who gloried in themselves. For both the greatness of the things given and the weakness of them that receive show His power; in that He not only gave great things, but also to those who are little. For he used the term "earthen" in allusion to the frailty of our mortal nature, and to declare the weakness of our flesh. For it is nothing better constituted than earthenware; so is it soon damaged, and by death and disease and variations of temperature and ten thousand other things easily dissolved. And he said these things both to take down their inflation, and to show to all that none of the things we hold is human. For then is the power of God chiefly conspicuous, when by vile it worketh mighty things. Wherefore also in another place He said, "For My power is made perfect in weakness." And indeed in the Old [Testament] whole hosts of barbarians were turned to flight by gnats and flies, wherefore also He calleth the caterpillar His mighty force; and in the beginning, by only confounding tongues, He put a stop to that great tower in Babylon. And in their wars too, at one time, He routed innumerable hosts by three hundred men; at another He overthrew cities by trumpets; and afterwards by a little and poor stripling, David, He turned to flight the whole army of barbarians. So then here also, sending forth twelve only He overcame the world; twelve, and those, persecuted, warred against.
