Preaching is not just morally edifying speech. It is not simply a pep-rally to excite the listeners to a day or two of penitential service. It is taking the dominion of God and placing it within the deepest reaches of the soul of those He is ministering to. It is screwing truth into men’s minds in such a way as to enthrall the heart with more of Jesus Christ. Preaching is a spiritual infection which ought to impregnate the hearer with the life of God and Christ.
