People need to limit their beliefs on hell to what the bible does say about it. The bible says that people are punished after judgement and not now.
"The Lord knoweth how to deliver the godly out of temptations, and to reserve the unjust unto the day of judgment to be punished." 2 Peter 2:9.
Sinners will be cast into hellfire at the great judgment day at the end of the world?not when they die. God would not punish a person in fire until his case was tried and decided in court at the end of the world. Nor would God burn a murderer who died 5,000 years ago 5,000 years longer than one who dies and deserves punishment for the same sin today.
So shall it be in the end of this world. The Son of man shall send forth his angels, and they shall gather out of his kingdom all things that offend, and them which do iniquity; And shall cast them into a furnace of fire." Matthew 13:40-42. "The word that I have spoken, the same shall judge him in the last day." John 12:48.
Yes, I was taught things not true about hell, and I think that most of us hear that too.
For with respect to that which he [Victor] most correctly and very soundly holds, namely, that souls are judged when they depart from the body, before they come to that judgment which must be passed on them when reunited to the body and are tormented or glorified in that same flesh which they here inhabited -- was that a matter of which you [Peter] were unaware? Who is so obstinate against the Gospel as not to perceive those things in the parable of that poor man carried after death to Abraham's bosom and of the rich man whose torments are set before us? (St. Augustine of Hippo, On the Soul and Its Origin, 11, n.8.)
