Enthusiasm is so important for pastors and Christian workers. I think it was Spurgeon who was asked,
"How come so many people come and hear you preach?"
He said, "I guess because I'm enthusiastic."
"How do you get enthusiastic?"
"Well, I'll tell you how to do it. Get a can of kerosene, pour it all over you, light yourself on fire, and they'll come watch you burn."
