This belief strategy is what I've called the "hedge my bets" strategy. Several counter arguments have already been ably stated...you may not be believing in the correct god, worshiping from fear, forcing belief where it doesnt exist. As an exBaptist(i always think of the skit 'ex-Police' from SNL) my favorite is the last. I'm off to find the quote which I think was attributed to Thomas Huxley about this type of belief which ended 'God help me I can believe no other way'. If it wasnt him or if I've butchered it in the paraphrase, it still reflects my view.
