"The final step in preparation for preaching, and perhaps the most important, is earnest petition for divine blessing on the message. I never feel properly prepared if I have not spent time with the Lord, asking him to give enlightenment, conviction, regeneration, and faith as the passage is preached. Luther said that theologians are made by oratio, meditatio, and tentatio, or prayer, meditation, and trial. The same may be said of the preacher, and first place is given to prayer."
