" The bell in the steeple may be well hung, fairly fashioned, and of soundest metal, but it is dumb until the ringer makes it speak. And . . . the preacher has no voice of quickening for the dead in sin, or of comfort for living saints unless the divine spirit [Spirit] gives him a gracious pull, and begs him speak with power. Hence the need of prayer for both preacher and hearers. "
