Pascal proposes that there are two decisions to make; to believe in God, or to not believe in God. If you don’t believe then you are risking damnation, but if you do believe, you have a chance of going to heaven. On the surface the best conclusion is quite obvious. Choose to believe, because if God does not exist there will be no repercussions, but if you choose not to believe and God does exist, then there will be major repercussions.
In reality, there aren’t only two options, though. There are several gods and denominations to pick from. What masqueraded as a fifty-fifty chance now shows to be a one in a million chance. Nearly all gods have been described as jealous. If you pick the wrong god and worship him, this will greatly anger the real God. Probability dictates that your best chance would be to not worship anything. Reason being, you will be acquitted of idolatry when your judgment comes (God really doesn’t like idolatry, see Ezekiel 8:3).
If you choose to worship a god, you have a one in a [insert number of gods here] chance of going to heaven, with the other percentage being your risk of perdition. Rather, if you worship no god, you might make a compelling case for yourself by stating you chose not to risk putting yourself at the top of his smite list.
Using the parameters of Pascal’s logic, one comes to a conclusion that doesn’t make the argument useful when proselytizing, or debating. Arguments of faith shouldn’t be based on arguments of probability, especially when the probability of being right is extremely low.
