If gawd exists and I believe, I get eternal salvation.Seems simple enough. But there are plenty of problems here.
If gawd exists and I do not believe, I get eternal damnation.
If gawd does not exist and I believe, I lose nothing (except maybe some earthly pleasures).
If gawd does not exist and I do not believe, I lose nothing.
Therefore it is only rational to believe in gawd out of the pure consequence of probability, since you only lose eternally if you do not believe.
1. Which gawd do I believe in? In order to maximize my probability of eternal jackpot, wouldn't I have to believe in the gawd of Abraham, as well as in Allah, Vishnu, Buddha, Zoroaster, Odin, Maynard, and any number of earth spirits?
2. Most protestant Christian denominations do not accept simple belief as one's ticket to Heaven. They require various forms of devotion, sacraments, works, and acceptance of Jesus' divinity as personal savyourah (best said with a Texas accent).
3. Gambling is against the dogma of most religions. Having gambling necessary for believe in gawd would probably not be an acceptable exception.
