Five young college students were spending a Sunday in London, so they went to hear the famed C.H. Spurgeon preach. While waiting for the doors to open, the students were greeted by a man who asked, "Gentlemen, let me show you around. Would you like to see the heating plant of this church?" They were not particularly interested, for it was a hot day in July. But they didn't want to offend the stranger, so they consented. The young men were taken down a stairway, a door was quietly opened, and their guide whispered, "This is our heating plant." Surprised, the students saw 700 people bowed in prayer, seeking a blessing on the service that was soon to begin in the auditorium above. Softly closing the door, the gentleman then introduced himself. It was none other than Charles Spurgeon.
