The Devil can so completely assume the human form, when he wants to deceive us, that we may well lie with what seems to be a woman, of real flesh and blood, and yet all the while 'tis only the Devil in the shape of a woman. 'Tis the same with women, who may think that a man is in bed with them, yet 'tis only the Devil; and...the result of this connection is oftentimes an imp of darkness, half mortal, half devil.
Martin LutherI compare it with a lie, which like to a snowball, the longer it is rolled the greater it becomes.
Martin LutherThe Holy Spirit is no skeptic. He has written neither doubt nor mere opinion into our hearts, but rather solid assurances, which are more sure and solid than all experience and even life itself.
