If men have been disobedient to God all through history.. going their own way.. glorifying themselves.. loving power and money etc etc..
What is God to do?
If He does nothing.. He doesn't care.
If He condemns the lot-- He has no grace.
But God is of Grace and Truth combined
the truth-- no man is perfect, God is perfect.. therefore there is a seperation between imperfect men and God. Because of men's disrespect of God's boundaries.. God had to create a place for people to go who would not follow Him.. who wanted to be seperate from Him.
This place was not part of God's original creation.. and was only meant for Satan and his minions. So to begin with it was not meant to be for people anyway.
So, if someone continually denies God their whole natural life.. what is God to do?
If He says.. oh that is okay.. you can come to my place anyway.. then He is a weak God and is also disrespecting the person's choice to deny Him.. and that person will be in a place they don't want to be!
Now.. the GRACE part..
God came down to earth in human skin as Jesus.. and sacrificed Himself on the cross so to bridge the gap between imperfect man and perfect God.. to pay for our imperfection.. so that whoever believes in Him will not perish but will have everlasting life.
He didn't have to do this! Man had been rebellious, going there own way.. they didn't deserve this! He would be justified to have left us alone.. and let men be seperated from Him forever...
but He is graceful.. VERY VERY graceful.
SO
1) Hell was not part of God's original creation.. but created out of necessity because men were going there own way and disrespecting His boundaries. It was meant for Satan and his minions.. not people. See Genesis begining-- no hell in that creation!
2) Hell is only for those who reject Jesus' salvation till the day the die--- if someone doesn't want to be with God.. why would He let them be with Him?
See Romans-- 'they are without excuse'
3) Hell is seperation from God.. eternal seperation.. but it is not mythilogical flames.. whips.. slaves and red demons with pitch forks- forget Hollywood's version of Hell!
4) When looking at crime.. when someone murders another.. the sentence isn't given for the duration of the crime.. but the weight of the crime. Now what is the greatest crime possible? Rejecting Jesus' salvation!! What should be the consequence for that? Seperation from Jesus! Why is it eternal seperation? Because of the WEIGHT of the crime.. not the duration.
5) God has also made it incredibly simple to have salvation. All a person needs to do is ask for salvation from Him! They don't have to go through a long series of rituals.. or turn their entire life around to have salvation! It is a FREE GIFT, not by works.. through faith in Jesus. See the book of Ephesians
6) God does not send people who are very young, before the age of knowing right from wrong.. to hell. They are under grace! They go to be with Him if they die before the age of accountability! See David's child who died..
7) God always warns people, either through prophets in the past or through his conviction now.. He does not just let someone go off seperated from Him.. without prompting them of His reality!
8) Greek words for hell from the Strong's concordance:
H7585
שׁאל שׁאול
she'ôl she'ôl
sheh-ole', sheh-ole'
From H7592; hades or the world of the dead (as if a subterranian retreat), including its accessories and inmates: - grave, hell, pit.
G86
ᾅδης
hadēs
hah'-dace
From G1 (as a negative particle) and G1492; properly unseen, that is, “Hades” or the place (state) of departed souls: - grave, hell.
G1067
γέεννα
geenna
gheh'-en-nah
Of Hebrew origin ([H1516] and [H2011]); valley of (the son of) Hinnom; gehenna (or Ge-Hinnom), a valley of Jerusalem, used (figuratively) as a name for the place (or state) of everlasting punishment: - hell.
G5020
ταρταρόω
tartaroō
tar-tar-o'-o
From Τάρταρος Tartaros̄ (the deepest abyss of Hades); to incarcerate in eternal torment: - cast down to hell.
The use of these different words is dependent on the context of the surrounding verse.. where it is used. But just because the Greeks and Hebrews didn't use the word 'hell'-- they still had the conception of a place of everlasting punishment.. eternal torment..place of departed souls.. world of the dead.. pit.. these meanings do not contradict the English.. but even expand on it! Give the world hell from the English more depth when looking at the Greek and Hebrew!
So that is my 2 cents.
Hell was not invented by teh Roman Catholic church.. unless you are prepared to argue they doctored the very earliest scriptures.. which does not fit with historical studies of the reliabilility and trustworthiness of scripture.. OT and NT.
