The story is told of a corporal who reported to a new regiment with a letter from his old captain saying, "This man is a good soldier and he'd be even better if you could cure him of his constant gambling."

The new C.O. looked at him sternly and said, "I hear you're an inveterate gambler; I don't approve, it's bad for discipline. What kind of thing do you bet on?

"Practically anything, sir," said the corporal. "If you like, I'll bet you $50 that you've got a strawberry birthmark under your right arm."

The C.O. snapped, "Put down your money!" then, stripped to the waist, proved conclusively that he had no birthmark, and picked up
the notes on the table.

He couldn't wait to phone the captain and exalted ... "That corporal of yours won't be in a hurry to make a bet after what I just did to
him."

"Don't be so sure," said the captain glumly, "he just wagered me $200 he'd get you to take your shirt off five minutes after he reported."

Belief (in God) is a wise wager. Granted that faith cannot be proved, what harm will come to you if you gamble on its truth and it proves false? ? If you gain, you gain all; if you lose you lose nothing. Wager, then, without hesitation, that He exists. -Blaise Pascal
