How to overcome the fear of death?

[Cinjin]

A dilema in our household is that my husband is a recently born again christian.

I'm truly sorry for you. It's always a shame to see any man brainwashed. Fear of death is a powerful persuader and it's compounded when you add Hellfire to it.
Vile christians.

After his father told me I'm going to hell the other day I asked him if it bothered him that I wouldn't be in heaven with him. He said he hadn't thought about it, clearly some discomfort to him, as he believes he will meet everyone again in the afterlife! More discord than the thought of what happens after death to him

Many many christians don't even believe in hell any more. What makes his father right? Answer: nothing, besides his own silly superstitions.

Death is coming for us all. I say let it be what it is.
Heaven and hell are ridiculous notions made up by people just like you and me. In the history of time, no man has ever wanted to say goodbye to the people he has loved the most in this life. It's the human condition. People will do and say anything to alleviate the sadness, the fear, and in some cases, the unending sorrow of saying goodbye for one last final time.
