Those who lapse from the Gospel to the Law are no better off than those who lapse from grace to idolatry.
Martin LutherWe may well lie with what seems to be a woman of flesh and blood, and yet all the time it is only a devil in the shape of a woman.
Martin LutherYes, would to God that I could persuade the rich and the mighty that they would permit the whole Bible to be painted on houses, on the inside and the outside, so that all can see it. That would be a Christian work... If it is not a sin but good to have the image of Christ in my heart, why should it be a sin to have it in my eyes? This is especially true since the heart is more important than the eyes, and should be less stained by sin because it is the true abode and dwelling place of God.
Martin LutherThe offering of [the body] is called a spiritual sacrifice because it is freely sacrificed through the Spirit, the Christian being uninfluenced by the constrainst of the Low or the fear of hell.
Martin LutherWhenever the devil harasses you, seek the company of men or drink more, or joke and talk nonsense, or do some other merry thing. Sometimes we must drink more, sport, recreate ourselves, and even sin a little to spite the devil, so that we leave him no place for troubling our consciences with trifles. We are conquered if we try too conscientiously not to sin at all. So when the devil says to you: do not drink, answer him: I will drink, and right freely, just because you tell me not to.
Martin Luther
