Thus, the wicked, under pressure of affliction, execrate God and blaspheme; the good, in the same affliction, offer up prayers and praises. This shows that what matters is the nature of the sufferer, not the nature of the sufferings. Stir a cesspit, and a foul stench arises; stir a perfume, and a delightful fragrance ascends. But the movement is identical.
St. Augustine, City of God, Book I, chapter 8
