Its no secret that the Roman Church created our vision of hell during the dark ages, when you you read Jesus Gospels, Jesus is very clear about the Kingdom of God, and Gods Gifts.....Jesus was clear in Luke 17:21 - Neither will they say lo here, or lo there, for behold, The Kingdom of God is within you.
So if Ephesians 2:8-9 : For by grace are ye saves through faith; and that NOT OF YOURSELVES: it is a Gift of God: Not of works, lest any man should boast.
Well, guess who's boasting? religious leaders who don't have a clue what Jesus is talking about, Jesus called out these self centered self righteous leaders right to their face.
Matthew 23:13 But woe unto you, scribes and Pharisees, hypocrites! for ye shut up the kingdom of heaven against men: for ye neither go in yourselves, neither suffer ye them that are entering to go in.
So, the Kingdom is Within you, not Hell, if you want to know what Hell is, its is when you become convinced that you don't share Gods light within yourself and your human ego mind convinces you fear is real, Jesus know's its a self imposed illusion and he knew the Scribes and Pharisees are servants to the ego...so is hell real, well, if your mind is powerful enough to create it, it can be real enough, but the reality is God didn't create it, you did.
Therefore if you accept God's gift of faith and accept you are saved by his grace as his gift to you, then you have entered into yourself and achieved salvation......Jesus made it simple, man made it complicated.
