Avira > do you really want to risk all of your tefilos because you couldn’t bring yourself to spend 7 dollars?
This is actually a great way to look at thing. You are paraphrasing Pascal wager – finite v infinite risk. For example, would you risk cutting off another car, risking that the driver is say an orphan or a widow, or any women, and she gets upset, an her prayer against you will be answered immediately. Obviously, no yareh shamaim will take such risk, QED.
