Those who are rich in things that are valued in the realm of the natural do not gain anything. They do not gain longevity. Rich and poor are in the same situation: they go through life quickly and do not stay for a long time. Thus “from all the toil at which they toil under the sun” one does not gain anything, no increase in natural qualities. But the one who toils and strives for things that lead to the eternal and to the invisible gains something: A human being becomes a god, an uncertain human being becomes a strong one, a coward becomes courageous.
"What
profit is there for a man in exchange for all his toil, which he toils under
the sun?" After the general opinion that all things are
vain Solomon begins to explain with regard to mankind: because men exert
themselves in vain in the toil of the world, amassing wealth, teaching
children, working their way towards glory, constructing buildings, and then are
taken away in the midst of their work by sudden death, they hear the words:
"Thou fool, this night your soul shall be required of you, then whose will
be those things that you have amassed?" [Luc. 12, 20.] Just as they make nothing for themselves in
exchange for all this toil, so they return naked to the earth from whence they
were taken.
So this is what the rich should do: not be haughty in their ideas, nor set their hopes on the uncertainty of riches, but on the living God, who bestows all things on us abundantly for our enjoyment; that is what they must do. But what are they to do with what they have? Let me tell you what: “Let them be rich in good works, let them be easy givers.” After all, they have the wherewithal. Poverty is difficult and grim. “Let them be easy givers”; they have the wherewithal. Let them share, that is, take some notice of their fellow mortals. “Let them share, let them store up for themselves a good foundation for the future.” “You see,” he says, “just because I say ‘Let them be easy givers, let them share,’ it doesn’t mean I want them looted, want them stripped naked, want them left empty. I am teaching them how to make a profit, when I point out, ‘Let them store up for themselves.’ I’m not telling them to do this so that they can lose it; I’m showing them where to transfer the account. ‘Let them store up for themselves a good foundation for the future, so that they lay hold of true life.’ ” So this one is a false life; let them lay hold of true life. After all, “Vanity of vanities, and all is vanity. What is this great abundance for man in all his toil, at which he toils under the sun?” So true life is to be laid hold of, our investments are to be transferred to the place of true life, so that we may find there what we give here. The one who transforms us also transforms those investments.
If it is a vain thing to do good works for the sake of human praise, how much more vain for the sake of getting money, or increasing it, or retaining it, and any other temporal advantage, which comes unto us from without? Since “all things are vanity: what is man’s abundance, with all his toil, wherein he labors under the sun?” For our temporal welfare itself finally we ought not to do our good works but rather for the sake of that everlasting welfare which we hope for, where we may enjoy an unchangeable good, which we shall have from God, nay, what God himself is unto us. For if God’s saints were to do good works for the sake of this temporal welfare, never would the martyrs of Christ achieve a good work.
