I have been rather reluctant to have a volume of sermons printed. My misgivings have grown out of the fact that a sermon is not an essay to be read but a discourse to be heard. It should be a convincing appeal to a listening congregation. Therefore, a sermon is directed toward the listening ear rather than the reading eye. While I have tried to rewrite these sermons for the eye, I am convinced that this venture could never be entirely successful.
