I thank God, honestly, that I do not fear death. I've seen the look in ppl's eyes when they were dying without Him; it is not easy.
I fully understand Paul's writing about "to die is gain." It was always power behind any depressively strong thoughts of ending what was a miserable (physically and psychologically) life. It is what is behind my ability to continue to live, in spite of all with which I contend.
But I have heard scholars of the Scriptures define heaven, and it's truly magnificent!
But, also, that we will have a purpose in heaven is important. It isn't that life is over and we just mull around with nothing to do... while those who have worked their whole lives might find that hopeful, it's good to know we will have a place, physically and "psychologically."
