"The Devil Can Kiss My Backside"

“It is the supreme art of the devil that he can make the law out of the gospel.  If I can hold on to the distinction between law and gospel, I can say to him any and every time that he should kiss my backside.  Even if I sinned I would say, ‘Should I deny the gospeI on this account?’ . . . Once I debate about what I have done and left undone, I am finished.  But if I reply on the basis of the gospel, ‘The forgiveness of sins covers it all,’ I have won.”-
