I tend to think of Hell not as a burning fiery inferno you might go to after death if you're bad, but rather as a kind of state of exile and disconnection from what is truly important and good and nourishing for us - by which I suppose I mean relatedness and Love.
We are all in a state of Hell at times, when we shut others out, cut ourselves off, allow ourselves to prioritise things that don't really nourish us and disconnect ourselves from what I refer to in my mind as "God" - i.e. that which is rather unknowable but to do with joy, laughter, grace, growth, humility, courage and all the rest of those good things.
Instead we can fall into envy, bitterness, paranoia, rage, greed and all the rest of those deleterious things.
For most people there is a daily to and fro between these two kinds of states.
For me, going to Church and praying to God helps me to make sure that the first set of states, the "nourishing" ones, have the upper hand most of the time, and win out over the deleterious states.
Its not really anything whatsoever to do with a powerful entity who is going to raise me up, or condemn, me forever.
