‘Are there actually people that have gone to hell or is it just a lie?’
No! It is not just a lie.
Jesus told the story of two people: one went to hell and one went to heaven. The story was to let people know that there would be a separation after we die. See Luke chapter 16 and verses 19 to 31. I have in my possession the story of a man who was dying (over 100 years ago) and wanted to tell someone before he died, of how he had died for several hours while working in a coal mine.
He was in jail and was made to work in a coalmine. The roof collapsed on him and he was buried for several hours. He was a criminal and a horse thief and had led a very wicked life. He told the story of what he saw and heard when he went to hell. It was dark and horrible.
He later did come back to life in the morgue. After a spell in hospital he quickly found a preacher and became a Christian but told no one about what he saw and heard because they put you in the lunatic asylum if you told such stories in those days. Only in his last days did he tell his story to a friend.
I am not going to tell about it here but be assured, punishment awaits wicked people.
Stories can be found on WWW – but do be careful. False stories do not honour God, nor do they fit with what the Bible says or they want to sell you something exciting. I spent some time on the www re. hell, and near death experiences, ‘I went to hell’ videos, etc. be careful! Be sure that the stories honour God, Jesus or the Bible and are not trying to ‘get you in’ or sell you something. Ask for guidance from God to be wise.
