I can see why the few on Goodreads who have read and rate this gave it 3 stars. It's not an indepth treatise nor very comprehensive in its treatment of the topic of sermon preparation. And yet, initially given as a series of lectures in the 1920s and then compiled in 1937, this handbook does provide the rationale for some profound principles on preaching. At only 90 pages, I thought it worthy of a few hours of time and thought.
