He has made every thing beautiful in its time: also he has put eternity in men's hearts, so that no man can find out the work that God does from the beginning to the end.
All Commentaries on Ecclesiastes 3:11 Go To Ecclesiastes 3
Evagrius Ponticus
AD 399
I have seen, he says, the material world that preoccupies human minds, that which God gave to the human race prior to its cleansing so that they would occupy themselves. He means here that the beauty of the material world is temporal, not eternal. For, after cleansing, the one who is pure no longer needs to view material things only as a diversion of the mind. Rather, he can also use them in spiritual contemplation. –.
