LOL...even Christians can't agree on the topic. Though there certainly are a few verses in the NT that are strongly suggestive of eternal torment (even if just who gets fucked isn't as clear). The Hebrew bible has only a few vague passages, that many Hellfire and brimstone preachers have tortured into supporting their dogma.
Here is one passage (this like has some others:

Matthew 25:31-46 When the Son of Man comes in his glory, and all the angels with him, then he will sit on his glorious throne. Before him will be gathered all the nations, and he will separate people one from another as a shepherd separates the sheep from the goats. And he will place the sheep on his right, but the goats on the left. Then the King will say to those on his right, “Come, you who are blessed by my Father, inherit the kingdom prepared for you from the foundation of the world.” . . . Then he will say to those on his left, “Depart from me, you cursed, into the eternal fire prepared for the devil and his angels. . . . And these will go away into eternal punishment, but the righteous into eternal life.”
