There’s a famous story told of five young college students visiting Charles Spurgeon’s London church to hear the famous “prince of preachers” give a message. Arriving early, they were greeted by a man who offered to show them around, particularly so they could see the church’s “heating plant,” despite the fact that it was a hot summer day.
Being polite, they followed the man to a door that he quietly opened. “This,” he told them, “is our heating plant.”
