Worrying about your hard work does not make the work any easier, and it only makes you less strong and courageous for doing it. Worrying about some misfortune which you cannot help makes the misfortune no less and only renders its endurance harder. Thus far even common-sense goes. Then religion goes farther, and assures us that even the hard things, the obstacles and the hindrances, become blessings if we meet them in faith, stepping-stones upward, disciplinary experiences in which we may grow ever into nobler, stronger life.
