I think that gamblers who believe that the spiritual side of life influences gambling and winning results appear after they start trying to predict their winnings. And when one of them actually wins, he connects these two events and begins to think that it really works. That the spiritual side of life is an influential part of gambling. And that this way you can also control the outcome of the game.
I would love to know, how about some one who experienced it happen before their eyes such that a prediction was gotten from some sort of spiritual consultation and when followed the way it was prescribed, they got to win the game, how then can you convince such person that they were just lucky and not their spiritual manipulations at work? Because I have heard from people who saw things like this play out before them and they had their bets won and they made money from it, this is something they did not experience when they did it all alone, they saw results after some spiritual involvements.
