Oh come on LG, are you tired?
God = Beautiful, charming woman
Belief in god = Marriage
Heaven (reward) = sex (reward)
actually its more the notion of god resting on a pyramid structure of qualities (of which "heaven" takes a prominent role) much like a beautiful and charming woman rests upon the said qualities of beauty and charm
to talk about either without these qualities (or at least address why these qualities are absent) is to be oxymoronic
(BTW Heaven holds greater ontological implications than issues of our mere reward)
