Justin does a good job of looking at what the Bible teaches about hell and heaven. I have written a book on hell: Lake of Fire – Terminal Punishment/Second Death; Eternal Conscious Torment; Universal Redemption ? which reaches the same conclusion as Justin, that unbelievers will face appropriate punishment but their ultimate end is a second death. At the moment it is only available as an eBook on Amazon.

“He who has an ear, let him hear what the Spirit says to the churches. The one who conquers will not be hurt by the second death.” Revelation 2:11

“Blessed and holy is the one who shares in the first resurrection! Over such the second death has no power,” Revelation 20:6

“Then Death and Hades were thrown into the lake of fire. This is the second death, the lake of fire.” Revelation 20:14

“But as for the cowardly, the faithless, the detestable, as for murderers, the sexually immoral, sorcerers, idolaters, and all liars, their portion will be in the lake that burns with fire and sulfur, which is the second death.” Revelation 21:8
