I think that hell essentially is separation from God forever. And that is the worst hell that I can think of. But I think people have a hard time believing God is going to allow people to burn in literal fire forever. I think the fire that is mentioned in the Bible is a burning thirst for God that can never be quenched.
Billy GrahamChurchgoers are like coals in a fire. When they cling together, they keep the flame aglow; when they separate, they die out.
