Context

“Let Wetzell know that David’s wars and battles were more pleasing to God than the fastings and prayings even of the holiest of the old monks, setting aside altogether the works of the monks of our time, which are simply ridiculous. CCCXIX. I never work better than when I am inspired by anger; when I am angry, I can write, pray, and preach well, for then my whole temperament is quickened, my understanding sharpened, and all mundane vexations and temptations depart. CCCXX. Dr. Justus Jonas asked me if the thoughts and words of the prophet Jeremiah were Christianlike, when he cursed the day of his birth.” source
