I think its a fantasy to not belive in hell...
I think it is a fantasy world where you think it's as simple as that. The understanding of hell is a really modern concept. The word hell originally came from the Saxon word hillion 'to cover up' From that we get hillion as an old English thatcher and we get heal from this as well (to cover up a wound) also helmet.
In Cornwall a thatcher is called a healer.
Thus the translation of the Hebrew sheol as hell in KJV time is a good one.
I am not suggesting that there is no "hell" I believe we need to take the NT claims seriously. But to think anyone has the definition of this is in the fantasy.
Jesus came to fulfill the law not to change it and our understand needs to still start with the OT, we need to balance our understanding of the eternal flame/lake of fire with:
"The candle of the wicked shall be PUT OUT" (Prov. 24:20).
"The wicked is reserved unto the day of DESTRUCTION" (Job 21:30)
"As wax melteth before the fire, so let the wicked PERISH at the presence of God" (Psalm 68:2).
"For yet a little while and the wicked SHALL NOT BE" (Psalm 37:10).
"He is like the beasts that PERISH" (Psalm 50:12).
"Let the sinners be consumed out of the land, and let the wicked BE NO MORE" (Psalm 104:35).
"They shall be AS THOUGH THEY HAD NOT BEEN" (Obadiah 16).
"They shall be AS NOTHING" (Isa. 41:11).
