Take this to heart and doubt not that you are the one who killed Christ. Your sins certainly did, and when you see the nails driven through his hands, be sure that you are pondering, and when the thorns pierce his brow, know that they are your evil thoughts.
Martin LutherThe Devil, it is true, is not exactly a doctor who has taken degrees, but he is very learned, very expert for all that. He has not been carrying on his business during thousands of years for nothing.
Martin LutherOne is not righteous who does much, but the one who, without work, believes much in Christ. The law says, 'Do this,' and it is never done. Grace says, 'Believe in this,' and everything is already done.
Martin LutherFor all works and things, which are either commanded or forbidden by God and thus have been instituted by the supreme Majesty, are 'musts.' Nevertheless, no one should be dragged to them or away from them by the hair, for I can drive no man to heaven or beat him into it with a club.
Martin Luther
