I think this is completely accurate, and I'm the perfect example.
My faith is the lowest it's ever been, dangling by a string. I still hold on, not because I truly believe, but because I refuse NOT to believe. Nothing's convinced me that religion is right or wrong, I've just slowly realized that I struggle to maintain my belief.
There are multiple reasons why I refuse to let go, but one of them is the notion that if there really isn't a God, then I don't really see the point in living. What's the point of a measly 80 years that result in nothing and everybody forgetting you? Why would any of us want to live such a disappointing and miserable life? Blow up the planet so we no longer exist and we'll be accomplishing just as much then as currently are in life. Art is pointless. Love will always end badly in death. Children are simply the beginning stages of descent to nothingness. I don't want to live in a world that is so absolutely pointless and miserable.
Why would any of you want to live such a miserable, disappointing life without any hope of any kind that matters? And for that matter, why do you (spoken generally) embrace that so much that you feel everyone else should also live such worthless, nothing lives?
This isn't being said disrespectfully, but in my eyes, without there being a God and something to look forward to post-life, there isn't any reason to live now. Nothing matters.
