I personally beleive there is a heaven and a hell. I beleive according to the bible. I beleive that we "see" what we want to "see". If we choose not to beleive then we can't be surprised when we see no evidence of that in our lives. Some who claim to be open minded are some of the closed minded people I have ever met. THe old pasage in the bible I think makes the perfect point and I feel it is 100% accurate. Lazuras the begger died and went to heaven and looked down and seen a rich man that passed him every day and the rich man asked God to allow his family to know and God replied it wouldn't matter whether the rich man returned to earth to warn them they still wouldn't beleive.
I have seen things that I would have never seen or experianced had I not been willing to open both my mind and heart. amazingly so have others around me and those that don't beleive in any thing after death or a greater power are the first to run, I've had them literaly state "don't want to kno I'm out of here" and basically run away while those that did beleive are more apt to say "what the heck? lets check this out". Again the heart follows the mind so if one refuses to see they will never be dissappointed and never see such great things that are past our persecption of this wourld..
