What is hell? Okay this is how I figure it: Let's see now if heaven is being within God's Grace and uniting with Him, then Hell would be out of God's Grace. In other words away from God.
So how can we be in God's Grace, and also what is God's Grace? Well in order to attain God's Grace we must accept Jesus as having redeemed us from our sins. Why you ask? Well I guess because when we accept His redemption, we are accepting ourselves as sinners, and by accepting our selves as sinners and realizing our limitations as humans, we are lessening
our pride. Grace then would be a continuous sojourn into a greater and greater sense of humility and thereby stepping completely out of oneself.
What if one doesn't repent for their sins before they die? Well then they have retained their pride and that becomes a barrier to God's Grace. Anyway hell is being without hope. So why don't we have hope after we die? I guess it's because if we die in a 'state' in which we blocked God out He cannot work our hearts and draw us closer to Him.
Saint Xenia of Saint Petersburg did an amazing thing. Her husband died when he was drunk, and was in an unrepentant state, so she took his name and donned his clothes, for thirty years. She humiliated him and that which he was the most proud of; the uniform he wore of the Preobransky Regiment, the most glorified regiment in Russia.
What she was doing was lessening his worldly pride after his death, in the same way God would have lessened it during his life if he was still alive. She's a great saint for her ordeal to save her husband's soul, and God did tell her before she died that her husband was saved.
Anyway you don't have to pay attention to anything I wrote other than that about Saint Xenia, because they are only my thoughts. I think though they explain hell quite easily...I mean can you imagine being without any hope? I can't imagine any torture worse than that.
