A United States Marine was attending some college courses between assignments. He had completed missions in Iraq and Afghanistan . One of the courses had a professor who was a vowed atheist and a member of the ACLU.
One day the professor shocked the class when he came in. He looked to the ceiling and flatly stated, “God, if you are real, then I want you to knock me off this platform. I’ll give you exactly 15 minutes.” The lecture room fell silent. You could hear a pin drop.
10 minutes went by and the professor said, “I’m still waiting.” It got down to the last minute when the Marine got out of his chair, went up to the professor, and lifted up his arm to strike him.
At that moment the professor was transformed into a 7-foot grizzly, wreathed in a halo of holy fire. The bear spoke: "Blasphemer thou art, thou thinkst to take the place of God? Those who deny me face eternal fire, but you who knows my work and yet commits the sin of Satan I curse a hundred times over!"
