" Good preachers...are effective teachers, good thinkers, with rhetorical skills, a good voice, a good memory, and the ability to recognize when to stop. They are diligent in their preparation, throwing heart and soul into their sermons, and they must be ready to take criticism. They should remember that they must patiently bear such criticism and dissatisfaction with their preaching. But above all, preachers must know that the Word of God has taken them captive and that God has called them to serve Him by proclaiming that Word. "
