Hell is an evolving concept in Christianity. In the Christian bible there is no reference to a fiery hell in the old testament. There is however references to an eventual resurrection in (for example) the book of Job and Daniel. In the New testament we find references to a place of eternal torment in fire. Why? Is a good question. Why was such a bad place not mentioned in the OT? I would think that would have been important to mention. Was its inclusion in NT writings due to interaction with the Greeks who did believe in such a place? I don't know, but I believe that my Jehovah's Witness friends here such as Deeje make some good points regarding this subject, and as I have said before, "I hope they are right about this subject" But ....I sure don't want to be there.
I find the concept of hell is evolving ' outside ' of the first-century Christian teachings.
Just as gospel writer Luke wrote at Acts of the Apostles 20:29-30 there would be false Christians.
Jesus too gave us the illustration about how genuine ' wheat ' Christians would grow together over the centuries with the fake ' weed/tares ' Christians until the ' harvest time ', or the soon coming ' time of separation ' on Earth as mentioned at Matthew 25:31-33,37.
There is a BIG difference between a non-biblical myth hell teaching and the Bible's temporary hell or grave.
It is good that you do Not want to be in hell. Jesus I would think also would Not have wanted to be in hell.
However, the day Jesus' died, according to Acts of the Apostles 2:27, righteous dead Jesus went to biblical hell until his God resurrected Jesus out of hell. If biblical hell was a permanent place Jesus would still be in hell instead of having the keys to unlock death and hell according to Revelation 1:18.
Biblical hell (grave) comes to a final end, but it's the wicked who will be destroyed forever according to Psalms 92:7
So, righteous mankind will either be in heaven with Christ, or the majority of mankind will be part of the humble meek who will inherit ( Not Heaven ) but inherit the Earth as Jesus promised.
