Janadele (and other Mormons who feel qualified), I have a question for YOU. The answer is subjective, and requires YOUR opinion. I'm sure it's not going to be found in the scriptures, or the official church doctrine. It's also possible that as you live in Australia, and may have never been to Salt Lake City, that you have no idea what I'm talking about. If that's the case, I understand completely.
Question: Why do so many LDS members appear to "glow"?
I swear, the vast majority of those born and raised in the LDS church shine. They have something peculiar to their complexions. I kinda noticed it several times with regard to various individuals when I attended the University of Utah. But when I attended an LDS church service, I looked out over the congregation and was suddenly struck by the idea that if we turned out the lights the whole group would glow in the dark.
I've been all around the country. As a result of being in dozens of foster homes, I've attended all kinds of churches. I've lived with health nuts, booze hounds, and everyone between. I've seen groups of people with alll kinds of common denominators. But the LDS folks are the only ones I've ever seen that shine like they're carrying lightbulbs in their garments.
I welcome your opinion(s).
