17 What defence then can we claim, or what excuse, when we pass by Him who is able to keep, and who is thankful for the trust giving in return great and unspeakable rewards, and in place of this guardianship commit our treasures to men who have not the power to keep them, and who think they grant us a favour, and pay us back at last only that which was given them. You are a stranger and a pilgrim with respect to the things here! You have a country which is your own in the heavens!
There transfer all—that before the actual enjoyment, you may enjoy the recompense here. He who is nourished with good hopes, and is confident respecting things to come, has here already tasted of the kingdom! For nothing ordinarily so repairs the soul, and makes a man better, as a good hope of things to come; so that if you transfer your wealth there, you may then provide for your soul with suitable leisure. For they who spend all their endeavours upon the decoration of their dwelling, rich as they are in outward things, are careless of that which is within, letting their soul abide desolate and squalid, and full of cobwebs.
But if they would be indifferent to exterior things, and earnestly expend all their attention upon the mind, adorning this at all points; then the soul of such men would be a resting place for Christ. And having Christ for its inhabitant, what could ever be more blessed? Would you be rich? Have God for your friend, and you shall be richer than all men!— Would you be rich? Be not high-minded!— This rule is suitable not only to things future, but to things present. For there is no such object of envy, as a man of wealth; but when pride is super-added, a two-fold precipice is formed; the war becomes fiercer on all sides.
But if you know how to exercise moderation, you undermine the tyranny of envy by your humility; and you possess whatever you do possess with safety. For such is the nature of virtue, that it not only profits us, as it respects futurity, but it also here bestows a present reward.
