The problem of evil is great. Many cannot tolerate to hear the name of evil, but they are faced with it every moment of their lives and therefore to leave this problem unsolved does not help. Besides this, everyone is ready to judge, to observe, or to take notice of the evil in another, not knowing that sometimes the surface of a thing is quite different from its depth. Maybe what seems evil has something good inside it, or what is good in appearance may have a spark of evil inside. By what standard can we determine evil and good, and who can judge the evil and good of any man? If one can judge something it is one's own evil and good. No one except God has the power to judge another. The sense of justice that is given to man is for judging his own actions, and if he judges himself he uses this sense best, because it is for this purpose that the sense of justice has been given to him.
