It really doesn't matter what the JW's teach nor what your mother believes. Ultimately, it is in the hands of God (if you believe in one). I have always loved how the organization feels like it can speak for God (if there is one). Case in point, the FDS articles where they state that God (if he exists) will be happy to appoint them over all his belongings. Yeah, that's right, they know exactly what God (if you choose to call him that) will do.
I will go out on a limb....if there is a God, and God's judgment day comes, the Watchtower organization will NOT make it out unscathed!
Just a thought (or maybe a few)
