[Sons to Glory!]

It seems like you are asking for empirical proof here. Kinda like asking, "Can you give me a practical example of God?" I can provide various evidences, but don't know it would rise to the level of proof you seem to be seeking.

And actually, even though I started this thread, I do not really consider this as anything like an essential article of the faith. It was more a curiosity as I wondered if those who don't see any difference between soul & spirit might tend to think of those who do as somewhat mystical.
