“In order to get attention, make your manner as pleasing as it can possibly be. Do not, for instance, indulge in monotones. Vary your voice continually. Vary your speed as well–dash as rapidly as a lightning flash, and anon, travel forward in quiet majesty. Shift your accent, move your emphasis, and avoid sing-song. Vary the tone; use the bass sometimes, and let the thunders roll within; at other times speak as you ought to do generally–from the lips, and let your speech be conversational. Anything for a change. Human nature craves for variety, and God grants it in nature, providence and grace; let us have it in sermons also.” – Spurgeon, Lectures to My Students, 132.
