“In the same fire, gold gleams and straw smokes; under the same flail the stalk is crushed and the grain threshed; the lees are not mistaken for the oil because they have issued from the same press. So, too, the tide of trouble will test, purify, and improve the good, but beat, crush, and wash away the wicked. So it is that, under the weight of the same affliction, the wicked deny and blaspheme God, and the good pray to Him and praise Him. The difference is not in what people suffer but in the way they suffer. The same shaking that makes fetid water stink makes perfume issue a more pleasant odor.”
St. Augustine of Hippo, City of God, Book I, chapter 8
