Consider also the different effects of prosperity and adversity. The former inflates us with pride; the latter humbles and purifies us. In prosperity we often forget to whom we owe all that we are; but adversity usually brings us to the feet of our Creator. Prosperity often causes us to lose the fruits of our best actions; but adversity enables us to expiate our past failings, and preserves us against future relapses. If you are afflicted by sickness, consider that God has doubtless permitted this to preserve you from the abuse you might have made of your health; for it is better to languish under bodily sufferings than gradually to destroy the life of the soul by sin.
