#shorts Part 44 — To Preach Properly
[…] the exercise of preaching is spiritual rather than vocal. For, although it be practiced by means of outward words, its power and efficacy reside not in these but in the inward spirit. Wherefore, however lofty be the doctrine that is preached, and however choice the rhetoric and sublime the style wherein it is clothed, it brings as a rule no more benefit than is present in the spirit of the preacher.
