He learns that language is power, in law, politics, poetry, church or state. A preacher must dominate his congregation the way some folk command animals, for man is like any other beast: sometimes you have to shout to get his ear, sometimes you must pin him down like a snake, or smack him on the nose like a disobedient mutt. But above all a preacher must speak in his own voice, forged of his own experience, for the Holy Spirit is the agent of the original, not the counterfeit, and that is why the Devil is jealous of the Almighty: the Devil is limited to imitation of what is, unable to create what is not. He is a trickster who can throw his voice but never once strikes an original note.
