I absolutely believe in the power of tithing and giving back. My own experience about all the blessings I've had in my life is that the more I give away the more that comes back. That is the way life works and that is the way energy works.
My doctor asked me if I smoked and I said only when I'm working golfing or drinking. Then I realized the only time I don't smoke is when I'm home. I didn't even realize I'd become a smoker.
