"I believe that you dont believe in god because you are afraid of death, because you don't know it well enough."
When I was a believer I was terrified of death because I "didn't know it well enough." I knew what the bible said, I knew what my church leaders said, but there were so many inconsistencies etc that confused me, I didn't know where the heck I was going to go.
Now, because I've actually considered those scriptures and doctrines from both sides, I assume that whatever happens when I die, it's not going to be as bad as I thought it was. And I'm a lot less afraid of death.
