The Christian concept of heaven is what many misconstrue as immortality in the flesh. The huge difference is that immortality in the flesh does not and cannot lead to boredom, due to the fact that advances are always being made and new things are always being created that would allow one to keep one's self entertained. The opposite cannot be stated for immortality in spirit form, for precisely what would there be to do except stand around in limbo for eternity? Early writers did not properly use their minds in creating the fictional place referred to as heaven.
