I believe in a creating force, I don't believe in religion, but religions do use the Bible to get their tithe, I just looked up, and one I found says the following:
"If we understand that grace always exceeds the law, and that the New Testament believers gave far above 10% of their own volition, we can begin to get an accurate perspective of New Testament tithing. Tithing is intended to train people to trust God, to break greed and selfishness off our lives, and build healthy spiritual habits that will release God’s blessing over our lives." Personally I think that's a great way of getting money.
