If the keys of the pianoforte complained of their unequal places in the octave, what would you answer? Jesus Christ gave a beautiful answer when asked why a person was blind, whether for his faults or the faults of his parents. He answered, "For neither, but that the works of the Lord may become manifest." The Qu'ran says that man is egoistic and asks the Lord of the universe why this or that is so, being unjust, and himself a slave of the law. It is as though a child watched a painter who had painted all his life and criticized him; the painter would answer, "I have done this all my life; you judge me according to your little experience, but I know what I am doing."
