As to why I don't believe in hell, its because I believe in God as our father, who loves us unconditionally..
I get that. I also believe that God is of infinite Mercy.
In fact, I couldn't understand the verses in Qur'an about hell when I first discovered Islam
in my 20's.
Coming from a C of E background, I found it abhorrent.
..but eventually, I came to understand.
Hell is inconceivable to me. If a god existed that created hell, I would reject that god. Life indeed can be hell, so why would God inflict it on us when we're dead?
..so you reject the Creator of the Universe, because He created a universe that contains evil?
Many, many people are suffering due to oppression and war.
Our Lord G-d is Lord of the past, Lord of the present, and Lord of the future.
We cannot, indeed, separate a life hereafter from this present life .. as far as our souls go.
..and that's it .. on the day of judgement, all of our souls will be laid bare.
Nothing will be hidden, as it is in this life [eg. what we say, and what we think might not tally]
Why would G-d inflict suffering upon us in ANY life!?
I think we are supposed to learn something as we go through this life.
We fall over, and we have to pick ourselves up .. and hopefully learn by our mistakes.
G-d does
NOT push us over .. it is of our own doing.
The same applies to the life hereafter.
i.e. Some people do not learn .. or
refuse to learn
