Spirtual Evolution Concept

I'm not so sure about the concept that an angelic being couldn't survive in hell. If you believe in fallen angels that would negate that argument. As far as angelic being surviving around us on earth, I think they do a better job than we can imagine. They seem to do just fine, some are stealthier than others and lurk in the shadows until they need to step into the light. Of course it's just my take on things but it all makes perfect sense to me.
