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] gives him a gracious pull, and begs him speak with power. Hence the need of prayer for both preacher and hearers.
C.H. Spurgeon
