Why no man must dare to think within himself- "I have conquered, and need strive no more"
A certain old man came to another and said, "I, indeed, am already dead unto the world." But the other, seeing the danger in which he was, thus warned him, "Be not ever sure of yourself while you remain in the body. Although perhaps you may say, ' I am dead unto the world,' yet there is one who is by no means dead to you even your adversary the devil. Surely innumerable are his evil ways, and immeasurable is his craftiness."
