For example, you can't spend any of the money in this world if you want to worship only me, because the money in this world is owned by another god. It is all pegged to the U.S. Dollar, which has the eye of Horus -- an Egyptian god -- on the back of it. If you can't use money, you can't buy food or anything else. Even if someone else supplies all your needs for you, they have to eventually use money, and thus worship the "GOD" on the money.
