I'm sorry your friend has died. I can't say whether he is exists now, or in the future. I'm not sure myself.
Realizing that the resurrection is no longer a sure thing, is hard to deal with. It made me sad when I thought of my Grandma and all the other nice people that have died, may never get another chance. I still leave a small possibility that there is something else, but I figure I will not know until I die.
For now, my grandma lives in my memories and all the happy times we had.
