I believe in afterlife, yes. But its hard to contemplate the idea of being in heaven or hell for eternity. As I think what happens if I die, I think "Oh, I only go to heaven forever. That's not too long." But realize that all I ever know, or think of is in my current life, which makes me go mad thinking about being alive, or dead, or with God forever. Like, I think all people want to think that they either,
1. Die and that's it
or 2. They die and go to Heaven, because they are scared of going to Hell forever.
I don't know if if this makes any sense, so Ill put it into other words:
I believe in heaven, but am scared of the idea of being somewhere forever, because I cannot contemplate it, because I only know what life is.
