It is impious to say that evil has its origin from God, because naught contrary is produced by the contrary. Life does not generate death, nor is darkness the beginning of light, nor is disease the maker of health, but in the changes of conditions there are transitions from one condition to the contrary.
Saint BasilMany a man curses the rain that falls upon his head, and knows not that it brings abundance to drive away the hunger.
Saint BasilNow, if you notice how the swan, putting its neck down into the deep water, brings up food for itself from below, then you will discover the wisdom of the Creator, in that He gave it a neck longer than its feet for this reason, that it might, as if lowering a sort of fishing line, procure the food hidden in the deep water.
