The greatest torture in hell will be the flaming fires. 2nd on the list IMHO is hell is the most stupidest, moronic, insane asylum on steroids in the whole universe. Jesus delivered us All from it. To reject him, well-we call that the biggest stupidity ever chosen.
The gospel message is too simple for a lot of people. Jesus died for our sins, he paid the price and in order to spend eternity with him you must believe and repent. You must believe he died and roads again.
