The Lord always helps me when I preach; provided I have earnestly sought Him in private… My chief help is prayer. Whenever I study a single part of divine truth, I always gain some light about it after praying and meditating over it. Extensive prayer is often difficult because of the weakness of the flesh, physical infirmities, and a full schedule. But no one should expect to see much good resulting from his labors if he does not spend time in prayer and meditation.
