The Son of God did not want to be seen and found in heaven. Therefore he descended from heaven into this humility and came to us in our flesh, laid himself into the womb of his mother and into the manger and went on to the cross. This was the ladder that he placed on earth so that we might ascend to God on it. This is the way you must take.
Martin LutherOur bodies are always exposed to Satan. The maladies I suffer are not natural, but Devil's spells.
Martin LutherThe 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 Luther
