It is quite a large sized carrot.
They are told to meditate and see yourself in paradise, to make it real to you. Well, if the GB knew that is was going to come then they would prepare the R&F much more differently than that.
Any body with half a brain would know that after a all out war between good an evil there will be plenty to clean up with little to no comforts.
It just shows that they GB really knows the truth about the "troof". If they really believed then the prep would be much more like some of the cults like the Branch Dividians, guns and all.
