Sometimes, I think that this Life is to observe and learn for the next Life where we can be activist angels... but some of us can't wait! I actually, however, really believe that all humans are fallen angels. During the Battle of Genesis, the Rebel angels fell to Earth and became humans. We lost our wings as we fell and that's why we have shoulder blades.
Angels are defined in the dictionary as "immortal, spiritual beings attendant to God; they are devine guardians." I believe in angels all around us- they they can rescue us and help us, animals too! I think everyone and everything has an angel, an energy, an aura about them, guiding them (just as i grabbed up my book to reference some more angel stories, my page marker fluttered up off the page as if it were alive, and on it was written "angels") There are rumors that Hubble has captured images of angels in space. The Vatican knows about these iamges, but apparently the images will not be released and noone who know about them wants to talk about them.
There is life and energy in all existence. Perhaps angels are conductors of the symphony of energy all around.
