Hereto I adjoin a parable. There were a certain man and wife; the woman by accident lost an eye, and was sorely troubled thereat. Her husband then said to her, “Wife, why are you troubled? “She answered, “It is not the loss of my eye that troubles me, but the thought that you may love me less on account of that loss.” He said, “I love you all the same.” Not long after he put one of his own eyes out, and came to his wife and said, “Wife, that you may believe I love you, I have made myself like you: I, too, now, have only one eye.” So men could hardly believe that God loved them till God put one of His eyes out, that is took upon Himself human nature, and was made man.
