I believe in God so I definitely believe there's a heaven. I also believe that there is a hell. John 3:16 "God loved the world so much that he gave his one and only Son. Anyone who believes in him will not die but will have eternal life." That's what I believe in.
Personally, I have been taught my many scholars in my life. One that studies religions. And I've learned that, all religions or mostly all speak of afterlife both heaven and hell. Some speak of re-carnation, meaning die and become revived, however as a flower if you will...
In my opinion, I am scared to die because I am afraid that I might not be able to do many things that I have a always wanted to do and I didn't enjoy life to the fullest. I am very scared, and greedy when it comes to life. I really don't want to die. This also might be irrelevant but one of my favorite quotes is "Our life, is made by the deaths of others" and if I die, I am more scared for my family than my conscious because like any loved one of mine, they are a huge part of me.
That sum's it up, oh and by the way... If I do die, I'd like to die while I am asleep. It is the end of the day by then anyway ;)
Every single person-(my belief) dies at some point. And we will all go somewhere. I believe everyone goes to heaven except the Rapist and such. But yeah I have no clue what it would feel like but no one needs to think about that now..
