Every preacher who has been around a while finds consolation in the promise of Isaiah that “the word shall not return void.” To preach well is success. I recall rallies when, in the course of his preaching, King would hold forth on the theological and moral foundations of the movement. The klieg lights and cameras shut down, only to be turned on again when he returned to specifically political or programmatic themes. “Watch the lights,” he commented. “They’re not interested in the most important parts.”
