Years ago, I attempted to discuss this topic with Jehovah's Witnesses in another Discussion Group. Looking back on the discussion, I found that I was never able to really get to the bottom of the subject.
I've never really understood Witnesses belief in the spiritual aspect of humans without some belief in a soul (or spirit). Since Witnesses do not believe that humans have a soul, then it stands to reason that they believe that we are simply physical beings. If this is the case, then God will ultimately judge humans on some physical aspect. This is pretty much equivalent to judging someone on their hair color.
The Witnesses belief that a persons "spirit" is simply their breath (which returns to God at death) is also confusing to me. I mean what is the point if there is no other significance to a persons spirit.
