Our promises: 1. Our goal is to bring you high quality Christian publications at reasonable and affordable prices. Therefore all of our works are complete and unabridged unless specifically stated otherwise, which means that unlike some other independent publications you get what you see and pay for. No unplesant surprises. 2. We endeavour to bring you updated editions of classic works. Therefore this work is not a scan, but is a completely digitized version of the original. 3. Unlike, many other independently published works, our publications are easy to read. Therefore you won't find illegible, faded, poor quality photocopies here. Neither will you find poorly done OCR versions of those faded scans either, with illegible "words" that contain all kinds of strange characters like £, %, &, etc. Our publications have all been looked over and corrected by the human eye. 4. We can't promise perfection, but we're sure gonna try! This little volume has its origin in a series of articles originally published in the columns of the South Western Presbyterian. Under the advice of judicious friends, they are gathered in this more enlarged and permanent form. The reader will perceive that it is the mere outline of what might easily be expanded into a treatise. It is brief, because intended simply to be suggestive of general principles.
