At the conclusion of the sermon, the worshippers filed out of the sanctuary to greet the minister. As one shook the minister’s hand, he said, “Thanks for the message, Reverend. You know, I bet you’re smarter than Einstein. ”Beaming with pride, the minister said, “Why, thank you, brother!” As the week went by, the minister began to think about the man’s compliment. The more he though, the more the wondered why anyone would deem him smarter than Einstein. So the following Sunday he asked the man, “Exactly what did you mean that I must be smarter than Einstein?” The man replied, “Well, Reverend, they say that Einstein was so smart that only ten people in the entire world could understand him. But Reverend, no one can understand you.”
