Scriptures of the New Testament describe hell as a place of eternal torment and a furnace of unquenchable fire. The people there are characterized by utter despair and hopelessness.
In Matthew 25:41, Jesus describes hell as an "eternal fire prepared for the devil and his angels." In verse 46 of the same chapter, he explains that those who are not ready when he returns, who have not followed him in this life, "go away into eternal punishment, but the righteous to eternal life." In Matthew 13:50 Jesus describes hell as a "fiery furnace" where there is "weeping and gnashing of teeth." Revelation 20:10 describes hell as a "lake of fire," where the devil is "tormented day and night forever and ever."
This description is contrasted to that of heaven in the following chapter, which is represented as a place where God dwells with man, and where his followers are "his people" and "God himself" is "their God." Revelation 21:4 continues on to show the stark difference between heaven and hell. While hell is a place of weeping, sorrow and death, in heaven God wipes "away every tear from their eyes" and promises that it is a place where there is no more death, mourning, crying or pain.
