How do you know it's "worked"? How do you know that a life without a Godly safety net might not have been even more edgy, exciting and rewarding? Did the people in your seminary tell you to apply the scientific method to the existence of God, by any chance? In all honesty, they should have done. I do, which is why I'm a heathen. There is simply no other conclusion to reach. Of course, if they taught you that the scientific method can be applied to some things and not others, they weren't being very, er, scientific, were they?
