“Foremost of all is the desire after another's wife or husband, and after extravagance, and many useless dainties and drinks, and many other foolish luxuries; for all luxury is foolish and empty in the servants of God. These, then, are the evil desires which slay the servants of God. For this evil desire is the daughter of the devil. You must refrain from evil desires, that by refraining you may live to God. But as many as are mastered by them, and do not resist them, will perish at last, for these desires are fatal. Put you on, then, the desire of righteousness; and arming yourself with the fear of the Lord, resist them. For the fear of the Lord dwells in good desire. But if evil desire see you armed with the fear of God, and resisting it, it will flee far from you, and it will no longer appear to you, for it fears your armour. Go, then, garlanded with the crown which you have gained for victory over it, to the desire of righteousness, and, delivering up to it the prize which you have received, serve it even as it wishes. If you serve good desire, and be subject to it, you will gain the mastery over evil desire, and make it subject to you even as you wish.”
