"The notion that faith in Christ is to be rewarded by an eternity of bliss, while a dependence upon reason, observation and experience merits everlasting pain, is too absurd for refutation, and can be relieved only by that unhappy mixture of insanity and ignorance, called 'faith.'" - Robert Green Ingersoll

Of course, Heaven doesn't exist.

Please recognize Maria Shriver's claim that her vision of Heaven "keeps [her] from falling apart" as a metaphor. Of course, she would not physically "fall apart" absent that vision. The notion that she would do so mentally or otherwise is scarier than that of a child "falling apart" upon learning the truth about Santa Claus.

Then there is Hell!!

Hell is possible but would God tolerate satanic spirits and contaminated souls? (The Singularity would not according to Father Edward Schillebeeckx, the famous contemporary theologian). According to Schillebeeckx, if you die in mortal sin, you simply no longer exist. That should make you think again about Heaven or is it simply another theological guilt trip?

Being good for the sake of goodness without rewards would be the better course but hey throw in a bit of Heaven to make it easier on the Day of Nevermore!!!
