It is a tough cookie SKBJ ... and her dilema it is universal ... she is just grieving right now and when this phase is over she may have a softer point of view, back to be an ever stronger JW with the hope that if she is good enough god will treat her sister differently, leave everything in Jah's hands, or seek elder's counsel because she was weak in her view of the wordly people ... god forbids she loves her "neighbor"! (I am actually commenting with a JW relative of mine in mind ... lol)
Within the Christian faith: The One who IS the resurrection - Christ Jesus, gave us the scale by which our "life" would be eternally preserved ... whether we believe in Him or not ...
Now when it comes to JWs, they do not have this kind o faith in JESUS, they regard him as "great teacher', just the son of their version of god, Michael, then they need the 8 guys in NEW YORK CITY, although with their lips they READ from the bible that HE IS THE RESURRECTION, they only READ this, they don't really grasp the magnitude of his words, HE IS the great I AM, HE IS everything including LIFE, RESURRECTION. They want to marvel and look for ways to make everythign so complicated and hard to obtain because they DON'T BELIEVE in the simplicity of the Gospel, that God so loved the world that he gave his only son for WHOMEVER believes in him shall not perish but have life eternal.
