Luther the Preacher

John Gerhard labeled Luther's sermon form "heroic disorder." It's heroic because Christ is the Victor valiant proclaimed as the sinner's only Champion in every sermon from every text. It is disorder because Luther had no concern for organizing material as to coordinate thoughts or subordinate thoughts. He just progressed from one idea to another. And he makes his transitions in a very casual manner.

I would love a copy of Fred Mueser's "Luther the Preacher" Augsburg.  Let me know if you have a copy.
