I do not know what hell is in the after life but I do have a very good idea of what it is for believers in this life.
Many believers build up their pride in the fact that they are believers, they will say look what I am and look what you are, it gets to the point they can do no wrong..
They get to believing they are something special of their own accord, maybe like Hitler or for that matter many t.v evangelists who we have seen fall.
All kinds of views on eternal punishment and eternal life but we do not know.
Pride comes before the fall and then comes the hell, we can not even point to the place where the pride began or where the fall began but we are in hell.
Now I am paraphrasing from memory. So put the claws away y'all.
