To properly discuss why God created "Hell" , one must first start with the words that have been translated for "Hell" in our Bibles. Ray Prinzing wrote:
Unseen Realm Called "Hell"
There are three Greek words which have been translated as "hell" in our commonly used King James or Authorized Version of the Bible.
HADES - meaning: the unseen state. And it corresponds to the Hebrew word "sheol," of the same meaning.
GEENNA - referring to the Valley of Hinnom, or Gehenna, which was the place of constant burning of refuse. So as such it stands in type for the place of purifying. It is referred to in the Old Testament by the name of TOPHET, located in the Valley of Hinnom, a place where many sacrifices were made and dead bodies consumed, or else were buried.
TARTAROO - the English form is Tartarus. Though this word isn't so well known, the meaning of it can best be obtained by a look at the verse where it is used, found in 2 Peter 2:4, to mean the abode where the wicked are sent and held until the hour of their judgment.
All three of these Greek words, HADES, GEENNA, and TARTAROO have been translated by the one Anglo-Saxon word of "HELL". There has, of course, been much confusion over this translating, using one word for three different words and their own peculiar meanings.
Added to all this we have another problem today, in that our own English words are changing their meanings over a period of years. For an example, we quote from a writing by Loyal F. Hurley: "Our old English word 'hell' is a derivative from the Saxon 'hillan' or helan,' or from 'holl,' a cavern, anciently denoted the concealed or UNSEEN PLACE of the dead in general. In parts of England men still say, 'I plan to hell my potatoes,' meaning, to bury them in a hole or pit, that is, a covered place. And formerly a lover would take his sweetheart into a 'hell' to kiss her, that is, into a place where others could not see." unquote.
Thus we can see also how far we have come in changing even this word HELL from what it once stood for, until now by popular usage it has come to mean some place of torment, and for some it even includes the thought of the lake of fire, which terminology is used in the book of Revelation."
I personally believe that "Hell" is remedial and that God will eventually save all people.
In Christ, Bubba
