Pascal's Wager: A Message For Unbelievers To Ponder.

'Belief 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.

I can't really agree with Pascal's Gambit, as this is sometimes called,  in the guise of simple guesswork - but surely it should prove sufficient motivation to 'seek to know the truth'. Moreover, you can 'prove faith' but only to yourself. 'Taste and see that the Lord is good.'
