We must never assume, then, that the sermon is ours to make or break. In the 1800s a famous organist traveled from town to town giving concerts. In each town he hired a boy to pump the organ during the concert. After one performance, he couldn’t shake the boy, who followed him back to his hotel. “Well, we had a great concert tonight, didn’t we?” said the boy. “I had a great concert,” replied the maestro. “Go home!” The next night, halfway through a fugue, the organ quit. The little boy stuck his head around the corner of the organ, grinned, and said, “We aren’t havin’ a very good concert tonight, are we?” If God isn’t pumping when we’re preaching, nothing happens.
