436. This may be further illustrated by the following comparisons: One cannot visit another who keeps a leopard and a panther shut up in his chamber (living safely with them himself because he feeds them), until these wild beasts have been removed. Who, when invited to the table of a king and queen, does not, before he goes, wash his hands and face? Who does not purify ores by fire and separate the dross before he obtains pure gold and silver? Who does not separate the tares from the wheat, before putting the wheat into his granary? Who does not prepare raw food by cooking it before it is made eatable and placed upon the table? Who does not beat the worms from the foliage of the trees in his garden, so that the leaves may not be devoured and the fruit thereby destroyed? Who loves and seeks to marry a maiden who is full of disease, and covered with pimples and blotches, however she may paint her face, dress finely, and labor by the charms of her conversation to affect him with the enticements of love? Man himself ought to purify himself from evils [and not wait for the Lord to do this without his cooperation, see n. 331]. Otherwise he would be like a servant, going to his master, with his face and clothes befouled with soot or dung, and saying, "Master, wash me." Would not his master answer him, "You foolish servant, what are you saying? See, here are water, soap, and a towel; have you not hands of your own and the power to use them? Wash yourself." And so the Lord God will say, "These means of purification are from Me; and your ability to will and do are also from Me; therefore use these My gifts and endowments as your own, and you will be purified."
