14 Therefore Christ says, “I will see you again, and your heart shall rejoice, and your joy no man takes from you.” A brief saying, but one that has in it much consolation. What then is this, “your joy no man takes?” if you have money, many are able to take away the joy that comes of your wealth; as, for instance, a thief, by digging through the wall; a servant by carrying off what was entrusted to him; an emperor by confiscation; and the envious man by contumely. Should you possess power, there are many who are able to deprive you of the joy of it.
For when the conditions of office are at an end, the conditions of pleasure will also be ended. And in the exercise of office itself too, there are many accidents occurring, which by bringing difficulty and care, strike at the root of your satisfaction. If you have bodily strength, the assaults of disease put a stop to joy from that source. If you have beauty and bloom, the approach of old age withers it, and takes away that joy. Or if you enjoy a sumptuous table, when evening comes on the joy of the banquet is at an end; for every thing belonging to this life is liable to damage, and is unable to afford us a lasting pleasure; but piety and the virtue of the soul is altogether the reverse of this.
If you have done an alms, no one is able to take away this good work. Though an army, or kings, or myriads of calumniators and conspirators, were to beset you on all sides, they could not take away the possession, once deposited in heaven; but the joy thereof continually abides; for it is said, “He has dispersed, he has given to the poor, his righteousness endures for ever.” And very justly; for in the storehouses of heaven it is laid up, where no thief breaks in, nor robber seizes, nor moth devours. If you pour out continued and fervent prayers, no man will be able to spoil you of the fruit of them; for this fruit too is rooted in the heavens; it is out of the way of all injury, and remains beyond mortal reach.
If when evil-treated you have done a kind action; if you have borne with patience to hear yourself evil spoken of; if you have returned blessings for reproaches; these are good works that abide continually, and the joy of them no man takes away; but as often as you remember these, you are glad and rejoicest, and reapest large fruits of pleasure. So also, indeed, if we succeed in avoiding oaths; and persuade our tongue to abstain from this pernicious practice, the good work will be finished in a short time, but the delight arising from it will be continuous and unfailing.
