Clement of Alexandria said:
By this, do you mean that you believe that it will be infinitely unpleasant, but not necessarily involve "burning"?
This excerpt from the Reformation Study Bible give a pretty accurate summary of my view:
Hell
The New Testament views hell as the final abode of those condemned to eternal punishment at the Last Judgment (Matt. 25:4146; Rev. 20:1115). It is described as a place of fire and darkness (Jude 7, 13), of weeping and gnashing of teeth (Matt. 8:12; 13:42, 50; 22:13; 24:51; 25:30), of destruction (2 Thess. 1:79; 2 Pet. 3:7; 1 Thess. 5:3) and torment (Rev. 20:10; Luke 16:23). These terms are probably symbolic rather than literal, but, if anything, the reality will be more terrible than the symbol. New Testament teaching about hell is meant to appall us and fill us with horror, persuading us that though heaven will be better than we could dream, so hell will be worse than we can imagine. These are the issues of eternity that must be realistically faced.
Hell is not so much the absence of God, as the consequence of His wrath and displeasure. God is like a consuming fire (Heb. 12:29), and His righteous condemnation for defying Him and clinging to the sins He loathes will be experienced in hell (Rom. 2:6, 8, 9, 12). According to Scripture, hell is unending (Jude 13; Rev. 20:10). There is no biblical warrant for speculations about a second chance after death, or an annihilation of the ungodly at some stage.
Those in hell will realize that they have sentenced themselves to be there because they have loved darkness rather than light, refusing to have their Creator as their Lord. They preferred the self-indulgence of sin to self-denying righteousness, rejecting the God that made them (John 3:1821; Rom. 1:18, 24, 26, 28, 32; 2:8; 2 Thess. 2:911). General revelation confronts everyone with a certain evidence of God, and from this standpoint hell has a basis in Gods respect for human choice. All receive what they chose, either to be with God forever, or to be without Him. Those who are in hell will know, not only that for their doings they deserve it, but that in their hearts they chose it.
The purpose of the Bibles teaching about hell is to make us turn with gratitude to the grace of Christ that saves us from it (Matt. 5:29, 30; 13:4850). For this reason Gods warning to us is merciful; He has no pleasure in the death of the wicked, but that the wicked turn from his way and live (Ezek. 33:11).
