Psalms 76:5

They slept their sleep, and found nothing. Truly this life is a sleep, and riches too: for when we seem to hold them, at once we lose them. Just as that which is written in the prophet: "As one who is thirsty sleeps, if he finds water he drinks; afterward, when he has awakened, the thirst itself remains," so also are riches in this world: while we hold them, we lose them.

This life is a dream; these riches flow as if in a dream. Hear the Psalm, O richest poor man: They have slept their sleep, and none of the men of wealth have found anything in their hands. Sometimes even a beggar lying on the ground, trembling with cold, occupied with sleep, dreams of treasures, and rejoices and is proud in his dreams, and does not deign to recognize his ragged father, and as long as he sleeps, he is rich. When he sleeps, he finds false joy; when he awakes, he finds true sorrow. Therefore, the rich man dying is like the poor man waking, who saw treasures in his dreams. For he was wrapped in purple and fine linen, a certain rich man, neither named nor to be named, a despiser of the poor lying before his door; he was wrapped in purple and fine linen, as the Gospel testimony is, and feasted sumptuously every day. He died, he was buried; he woke up, and found himself in flames. Therefore, he slept his sleep, and this man of wealth found nothing in his hands, because he did nothing good with his hands.

"There have been troubled all the unwise in heart" (ver. 5)....How have they been troubled? When the Gospel is preached. And what is life eternal? And who is He that hath risen from the dead? The Athenians wondered, when the Apostle Paul spake of the resurrection of the dead, and thought that he spake but fables. But because he said that there was another life which neither eye hath seen, nor ear heard, nor hath it gone up into the heart of man, therefore the unwise in heart were troubled. But what hath befallen them? "They have slept their sleep, and all men of riches have found nothing in their hands." They have loved things present, and have gone to sleep in the midst of things present: and so these very present things have become to them delightful: just as he that seeth in a dream himself to have found treasure, is so long rich as he waketh not. The dream hath made him rich, waking hath made him poor. Sleep perchance hath held him slumbering on the earth, and lying on the hard ground, poor and perchance a beggar; in sleep he hath seen himself to lie on an ivory or golden bed, and on feathers heaped up; so long as he is sleeping, he is sleeping well, waking he hath found himself on the hard ground, whereon sleep had taken him. Such men also are these too: they have come into this life, and through temporal desires, they have as it were slumbered here; and them riches, and vain pomps that fly away, have taken, and they have passed away: they have not understood how much of good might be done therewith. For if they had known of another life, there they would have laid up unto themselves the treasure which here was doomed to perish: like as Zacchaeus, the chief of the Publicans, saw that good when he received the Lord Jesus in his house, and he saith, "The half of my goods I give to the poor, and if to any man I have done any wrong, fourfold I restore." This man was not in the emptiness of men dreaming, but in the faith of men awake....
