I believe in a literal interpretation of the King James Bible, but studying it as literal truth has ironically gotten me to the point where I tend to agree with Universalism (that the most likely outcome for our universe is that God gets His way and everyone is brought to Salvation). I think one of the keys is the Harrowing of Hell.
There are definitely many references to hell before Christ's death (as in people who were currently in hell...the Rich Man from Luke 16...but also righteous men like Abraham, David, Samuel, King Saul, Saul's son etc (they are all referenced as descending down to Hades after death.... It seems that almost everyone went to hell under the Old Covenant). But it seems to me that all of that changed with Christ's death and the Harrowing of Hell.
As far as many of the the verses which include Christ's warnings about "Gehenna" in Matthew were warnings on a societal level. Passages like Matthew 25 seem to be referencing the impending doom of Jerusalem.....and what some might call "supersession" ...the idea that the Jewish people would no longer be the only race/ tribe that could be redeemed, and that a New Covenant had been established in the context of Christ's death. Indeed, many of Christ's warnings in Matthew seem to refer to an old Guard being "thrown out into the darkness" in favor of a new Guard (presumably comprised of both Jews and Gentiles who had accepted Christ). Christ also warned that this separation of the "sheep and the goats" would herald the "end of the age" but also predicated these warnings with time signifiers such as "These things will all happen before this generation passes away". It's interesting that Christ uses "Hades" in the story of Lazarus and The Rich Man but uses "Gehenna" when talking about the Sheep and the Goats. But what really convinces me that Christ's warnings in the Olivet Discourse are not about Hell (the same Hell that is referenced in the story of Lazarus and the Rich Man) is that this entire sequence (including the warnings about the Sheep and the Goats and the references to kolasis and eternal destruction) is predicated with that time signifier- "These things will all happen before this generation passes away". Why would general warnings about Hell be pinned to any one time frame or generation? And of course much of what Christ predicted in the Olivet Discourse (or the "Little Apocalypse") did come true. Many theologians claim that he was accurately predicting both the destruction of the Jewish Temple in 70 AD and the transition to the Christian (New Covenant) era of human history.
Now back to Hades....Christ uses the word Hades to tell the story of Lazarus and the Rich Man. But what happened to Hades upon Christ's death? Ephesians 4:9 says "..He also had descended into the lower parts of the earth..." 1st Peter 4:6 says "For this reason the gospel was preached also to those who are dead, that they might be judged according to men in the flesh, but live according to God in the spirit."...and then 1st Peter 3:18 says “For Christ also died for sins once for all, the just for the unjust, in order that He might bring us to God, having been put to death in the flesh, but made alive in the spirit; in which also He went and made proclamation to the spirits now in prison, who once were disobedient, when the patience of God kept waiting in the days of Noah....”. And there are other passages of course...but the main point is that Christ descended to free the dead spirits (presumably including the Rich Man and Lazarus).
One of the most significant aspects of this Biblical timeline is that there is no mention of anyone being in Hades after Christ's death (The Lake of Fire mentioned in Revelation is in the context of a future event that I will discuss in a moment). At no point in the New Testament AD (after Christ's death) is there any mention of anyone being in Hell (at least no mention that I have been able to find...feel free to correct me if I am wrong). To the contrary, it reiterates the freeing of those in Hell. As Acts 2:31 notes- "David, foreseeing this, spoke concerning the resurrection of Christ that ‘His soul was not left in hell, neither did His flesh see corruption." (notably this verse reverts back to the root word of Hades...after the root word of Gehenna had become commonplace in the New Testament). The only reference to a possible Hell that I can find in the New Testament after Christ's Death is in 2 Peter 2:4 where it refers to angels being currently bound in Hell awaiting judgement- "For if God spared not the angels that sinned, but cast them down to hell, and delivered them into chains of darkness, to be reserved unto judgment" Interestingly, Hell here has the root word of "Tartarus" (Is that the only use of "Tartarus" in the Bible? I havent been able to find it anywhere else)..
The references to a future Hell in Revelation are (I suspect) something totally different. These references use "Lake of Fire" instead of the other root words (although "Hades" is brought back in a separate context as an anthropomorphized presence which rides alongside Death before being engulfed by the Lake of Fire). I believe that the references to Hell and the Lake of Fire in Revelation are also on a societal level (similar to the references in the Olivet Discourse but on a much more apocalyptic scale)....but thats a bit more complicated and involved topic...Ill only open that can of worms if people are interested..
