Do light beings still have, or have to have, faith in anything? Was the fall of the fallen angels a crisis of faith on their part in any way? Were they once enlightened and lost it?

This is an interesting point to ponder, the fate of the fallen angelics, how it came about that they turned away from the light and fell from grace, so to speak. That is a good description because it was not divine condemnation, judgment, and punishment that resulted in their becoming disconnected from the divine, it was a process they chose and initiated and then lost control of, and were unable to find their way back again. Nor could they reach for help, which would have been granted, and so the analogy of falling as though another force was at work plummeting them to the depths, out of control, is a beautiful and apt description of their dilemma. In some ways, this is akin to human suffering where you are in a state of disconnection yearning for a reunion with the divine, suffering many attacks and onslaughts by interlopers wanting to undermine and destroy you, but being in such a state of ignorance and unawareness you do not appreciate the wolf at your door because you cannot see it with your eyes and hear it with your ears. It is an energy attacking from within; as it weakens you steadily, you have less and less inclination to look for a divine solution, to turn to prayer, or request divine healing for anything. Even to the trained and educated human exposed to religious teachings but who has turned away and adopted a secular view of things, that seems at best a false hope or a dim one, and most probably giving in to superstition or a human folly that has fallen by the wayside and been rejected by a growing number of fellow humans as having outlived its usefulness, and has become more a threat in some ways than a blessing because it gives people yet another reason to kill one another if their religious leanings differ. This state of affairs is the biggest of tragedies because it is a surrender to ignorance and a denial of the miracles around you. The very existence of creation and all of its manifestations, especially the human being and the very miracle of incarnation, coming and going in spirit form, to and from a physical body with the content of information to create something like you out of generic energy is a miracle indeed. To look for prosaic explanations and settle for a simplistic view of reality is not only illogical, it is a denial of reality when trivializing the miracle of existence of everything you see around you. So you yourselves in your human experience, and having a shaky faith in us many times or an absence, as the case might be, are following the template of the spirit meddlers who sought a more exalted existence and in the process separated themselves from divine influence, thinking if they were more in charge they could make more good things happen for themselves. So it was a selfish notion through ego that started that process of "falling from grace," meaning, "A growing disconnection from the divine from whom all grace is bestowed, to make the miracles happen and sometimes to save you from yourselves." Our paradigm established for you, of free agency and free will, is a demanding one because it means you are on your own. It is at once a test of you and a challenge to create many potential dilemmas and, in the process, take risks. If you fail the test, the consequences might be dire. So we would point to the plight of the fallen angelics as a cautionary tale in what can happen if you surrender power and control to chance and put your faith in others who are disconnected as well, thinking they know better or they can save you if there is a problem of some kind. When you leave the divine out, you are cutting your lifeline and the consequences will eventually be disastrous from making that choice.
