G. Campbell Morgan once observed, “The preacher should never address a crowd without remembering his ultimate citadel is the citadel of the human will. He may travel along the line of the emotions, but he is after the will. He may approach along the line of the intellect, but he is after the will.
“When preaching becomes merely discussion in the realm of the intellect, or — forgive my use of the word– fooling in the realm of the emotions, and when preaching ends in the intellectual or emotional, it fails. It is successful only when it is able to storm the will under the will of God. The preacher comes with good news; but he does not come with something to be trifled with. His message has an insistent demand, because he comes from a King.” (from Preaching by G. Campbell Morgan, 1955)
