"And, the alternative? This life is all there is?
"
That's not the only alternative, you know. Every religion has some sort of way of dealing with the aftermath of death. Christianity is not the only religion with an afterlife of some kind.
Indeed, only the atheists, like myself, believe that this life is all there is. For me, that belief makes this life all the more important.
I cannot express how sorry for you I am.
I hope someday that you will see what you don't see at present. Take care.
Funny you should say that; when my son died, the book that helped me most was a book about how different religions around the world handle death.
