Hell is a real place, Jesus told the story of the rich man and Lazarus which is the most straight forward presentation of Hell in the Scriptures. The basics of Hell are thus: Prior to the cross, there was a Paradise section of Sheol where the righteous abide until Christ, after His death, went and got the Old Testament Saints and took them to Heaven leaving the Paradise section empty. There is a torment section of Sheol (Hades/Hell) where the unrighteous and the wicked remain today. Every unbeliever that has ever died has consigned themselves to this place of fire, sulfur, and eternal damnation. At the end of the Millennium, at the Great White Throne Judgement, Hades will give up its dead and all will face the final judgement. Those not found in the Lamb's book of life will be cast forever into the Lake of Fire.
During the Millennium, there will be a literal gateway to Hell where men will look upon those who have transgressed against the Lord. Isaiah 66:22-24 "For just as the new heavens and the new earth Which I make will endure before Me," declares the LORD, "So your offspring and your name will endure. And it shall be from new moon to new moon And from sabbath to sabbath, All mankind will come to bow down before Me," says the LORD. "Then they will go forth and look On the corpses of the men Who have transgressed against Me. For their worm will not die And their fire will not be quenched; And they will be an abhorrence to all mankind."
You do not have to go there, you can repent of your sins and accept Christ today. I beg of you, do not send yourself to this terrible place!
