We all forget that money is used to give us the life we want. We don't necessarily want the money itself, but what it brings to us. Freedom from worries and more time to do what we love to do.
The Second Noble Truth of Buddhism states that the origin of suffering is the attachment to the various kinds of desire.
This is what tithing helps us escape, in a sense. By truly giving 10% of every cent we make, we get over the fear and attachment that there is not enough money to go around.
Edwene Gaines believes that you should tithe to anyone/anything that gives you spiritual food. It doens't have to be 10% to one area, but over all it must add up to 10%. After all, that is what tithe means, right?
Remember, the more tightly you hold on to something (love is the most used example), the more it wants to get away. The same is true of money. Don't hold on to it so tightly, and it will want to stay around.
Now, 10% is just a start. It is necessary. Did you know that the top 2% of the richest people in the world give more than the other 98% combined? This is not because they have the money to give, but rather they are rich because they gave when they still had nothing to give.
Like Earl Nightingale said in "The Strangest Secret," many people have the mindset of the person sitting beside the wood heater saying "First, give me heat then I will put in some wood to burn," when the only true way to prosper is to put the wood in first and then let the heater give you the needed warmth.
So start giving 10% of your earnings away, and watch your life accelerated in new directions you never thought possible. It's scary isn't it? Do it anyways. That is what faith is, right?
As Emerson said, "You cannot outgive God."
