As the whole of nature is made by God, so the nature of each individual is made by himself; and as the Almighty has the power to change His nature, so the individual is capable of changing his nature. Among all the creatures of this world, man has the most right to be optimistic, for man represents God on earth, God as Judge, as Creator, and as Master of all His creation. Man is master of his life, of his own affairs - if he only knew it.
