Get thee behind me, Satan, Mark viii. 33.
It is true that there is nothing but Good; but the question for each one to decide is, whether he has so far realized this fact that he has really and truly put behind himself, and entirely cast out, the illusion of evil. So long as evil seems to exist, that seeming must be avoided just as carefully as though it were real. It is not enough to say, "Get thee behind me, Satan." If Satan appears, he must be thrust resolutely behind thee. Otherwise, though thou commandest him, he may go by thy side unseen, and direct thy path to thine own downfall.
