When good and bad men suffer alike, they are not, for that reason indistinguishable because what they suffer is similar. The sufferers are different even though the sufferings are the same trials; though what they endure is the same, their virtue and vice are different. For, 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 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.

~ Augustine
