Jesus said he'd come back in judgement of all people who ever lived. Matthew 13:47-50 BBE) reads, "Again, the kingdom of heaven is like a net, which was put into the sea and took in every sort of fish: When it was full, they took it up on the sands; and seated there they put the good into vessels, but the bad they put away. So will it be in the end of the world: the angels will come and take out the bad from the good, And will put them into the fire: there will be weeping and cries of sorrow."
Notice that it's the Kingdom of Heaven which Christ was describing. The church has both saved and unsaved individuals in it. Jesus told a parable about a farmer sewing good seed and an enemy spreading weed seeds on the land during the night. But the weeds weren't pulled up lest they also root up the good wheat. At harvest time, meaning the end of this wicked age, the wheat was gathered up but the look-alike tares were burned. Matthew 13:40 (BBE) warns, "As then the evil plants are got together and burned with fire, so will it be in the end of the world."
Jesus likewise described the fate of the phoney Christians in Matthew 7:22 and 23 (BBE). "A great number will say to me on that day, 'Lord, Lord, were we not prophets in your name, and did we not by your name send out evil spirits, and by your name do works of power?' And then will I say to them, 'I never had knowledge of you: go from me, you workers of evil.'"

When Christ comes again, every person will be separated according to their nature. The righteous will be on his right and the wicked on his left. As Matthew 25:31 and 32 (BBE), using a livestock metaphor, explains, "But when the Son of man comes in his glory, and all the angels with him, then will he be seated in his glory: And before him all the nations will come together; and they will be parted one from another, as the sheep are parted from the goats by the keeper."
Furthermore, hell is so horrific that the Bible uses metaphors such as fire, darkness, and worms to describe it's torments. Mark 9:48 and 49 (BBE) ends Christ's description of that place of eternal punishment. "Where their worm is ever living and the fire is not put out. Everyone will be salted with fire."

I hope you're a child of the Lord and not of your father, the Devil. So many folks assume they'll be paradise bound when they die but they'll end up incarcerated with demons eternally. That's why I'm writing my book, You Think You're Going to Heaven? I want none of my readers to end up in such a horrifying place.
On Saturday, I'll post about a sunken ship and that was immortalized in a song by Gordon Lightfoot.
