Have you ever read any books about Near Death Experiences?
NDEs — they should prove to you that the soul is alive.
I recommend a book by Dr. Jeffrey Long because it has the scientific as well as the heavenly (or otherwise) accounts.
Evidence of the Afterlife: The Science of Near-Death Experiences
I believe in a living soul after death. I look forward to going to heaven. However, if a soul is thrown into Hell, can a pray get God to change his mind? I don’t think so.
