You will have passed up some fun, but there would be rewards as well. Now suppose that you act as though God is not. You hang out in the casinos and fleshpots and place 'me' above all else. And suppose you are wrong on this side of the bet. You may have had a lot of goodies in the span of your lifetime, but you will suffer damnation into eternity.
Nobody wants that.
The value of the bet that God is, is infinitely greater than the value of the bet that God is not. The probability that God is or God is not is irrelevant. Now translate this line of analysis into business decisions. Suppose you are planning to launch a new product into another country where the market for this kind of product is growing vigorously. The probabilities of success appear to be high, but this market is also highly competitive.
