The point of Georgia's rain in a drought period at a most critical time when drinking water reservoirs were within days if not hours of drying up to the point where water would not longer flow into the inlets is a matter of record and history.
Link? The one I found stated a three month supply before it ran out and it rained about two weeks later. Good things happen all the time to people that never pray. If prayer was that powerful this should be a lot better world.
