We all need something higher than us.  Something beyond our knowledge, to try to comprehend something incomprehensible.  Humans aren’t the same as everything else on this earth, we’re not motivated by instinct alone, nature doesn’t decide our actions.  We all have a free will.  But with this free will, we still can’t help but desire for something higher, and its not like a physical hunger, where we eat when we’re empy and we get full and become empty all over again. Our spiritual hunger goes beyond that.  The more of GOD we receive, the more we DESIRE.  And we don’t desire because of emptiness, cause we find ourselves wanting more and more in our state of fulfillment. God doesn’t refill…he fulfills beyond our brim of humaness.
