20 He teaches us that riches are not only to be contemned, but that they are also full of peril; that in them is the root of seducing evils, that deceive the blindness of the human mind by a hidden deception. Whence also God rebukes the rich fool, who thinks of his earthly wealth, and boasts himself in the abundance of his overflowing harvests, saying, “You fool, this night your soul shall be required of you; then whose shall those things be which you have provided?” The fool who was to die that very night was rejoicing in his stores, and he to whom life already was failing, was thinking of the abundance of his food.
But, on the other hand, the Lord tells us that he becomes perfect and complete who sells all his goods, and distributes them for the use of the poor, and so lays up for himself treasure in heaven. He says that that man is able to follow Him, and to imitate the glory of the Lord's passion, who, free from hindrance, and with his loins girded, is involved in no entanglements of worldly estate, but, at large and free himself, accompanies his possessions, which before have been sent to God. For which result, that every one of us may be able to prepare himself, let him thus learn to pray, and know, from the character of the prayer, what he ought to be.
