This book greatly expands upon the style of public speaking manuals offered by educational groups such as the Toastmasters International and the material on different types of sermons found in the classic "On the Preparation and Delivery of Sermons" (1870, John A. Broadus). It is designed like a manual to progress systematically from easy to harder preaching styles. However, if you are an experienced preacher just skip ahead and work on those areas where you need more improvement. On the other hand, some lessons like How to Read Scripture Aloud contain concepts that take a lifetime to master. These are such important tasks that even if you are a seasoned professional you may want to review them from time to time.
