One calm and scenic Saturday afternoon in May of 1857, a young Charles Spurgeon found himself standing underneath a mulberry tree with a fellow minister. The weather was calm, not a leaf stirred. During their conversation a gentle breeze passed through, rustling the leaves above their heads. Spurgeon suddenly interrupted the minister and said with an excited hush, “Stop! keep quiet! don’t speak!—there! My sermon for to-morrow; ‘The sound of a going in the tops of the mulberry trees.’”
