Take Pascals Wager for example.
The problem I've had with Pascal's wager is the negative aspect associated with the outcome that God exists but one doesn't believe. This relies on the whole idea of a judgmental God or a God that says that if you don't believe in me (or my son) then you are banished to hell. I find the idea that a being so powerful to be God would have such a need to have his (her) ego stroked irrational. God (if he exists) is much more likely to judge us on our life's work, our karma, if you will. In fact God would not necessarily have to do this judging, He would set up a system that provides this outcome, aka - karma. Also, what if one believes in the wrong God, will this judgment be worse? What about the poor children who have no other information than to believe in Allah or Krishna? The business about the ONLY way to heaven is through Jesus is also ludicrous to me. That is way too easy, just come to Jesus just before you die? Really?
If we are judged at all, it will be based upon how we treated our fellow man and what we contributed to the welfare of the world. Woe be it to those who set themselves up as judges and pass spiteful and mean spirited sentences!
In reality I think the metaphor has much more to do with how we experience our life here on earth. Give forth goodness and mercy and you shall reap goodness and mercy. That message has been completely lost on those caught up in the quest for heaven.
