What profit has a man of all his labor which he takes under the sun?
All Commentaries on Ecclesiastes 1:3 Go To Ecclesiastes 1
Didymus the Blind
AD 398
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.
