I think they do as suggested by Lucifer’s behavior. The higher, closer-to-Paradise beings may be unable to exalt themselves, however.
Keeping directly to your question, Keryn, my first thoughts remind me of the Master’s ride into Jerusalem on a donkey instead of a white stallion. He was humble.
Extrapolating, I am wondering if the plan for the higher celestial personalities is to be humble, reducing their presence somewhat to reduce risk of dominating the Constellation Fathers. The Fathers rule over the systems and coordinate as three in their ministry. The highest authority within the constellation is this team and they are observed as primary. Teamwork is a major theme in the book. It is possible the Vorondadek’s are emphasized as a coordinating team model for ascending mortals learning this very important lesson.
Recall a major cosmic detail in the book is the condescending step-down of Sons from Paradise continuing in the local universes; those personalities serve rather than to be served, as Jesus taught. It is possible the Faithfuls of Days intend humbleness and are setting a Paradise example. Is this too much extrapolation?
Doing a word search on “ego” I found hits discussing human ego, but nothing on higher personalities. Somehow it seems the theme throughout the book does not include competition among celestial beings for status. Grabbing and competition are immature human concepts.
Also, Recall there is some degree of withdrawal from “up front” of higher personalities as they serve at lower levels, such as the prime system manager is sovereign over his realm. This person is not a Paradise being. On the constellations a team of three Vorondadeks are primal management. The Faithfuls of Days seem to be on duty for advice and counsel, but are restrained unless requested to be involved. Of course, wise constellation fathers do involve them. It boils down to respect of a high order for the Michael plan set in place. The arrangements and relationships could be different in other local universes and super universes.
This is the only concept I see presently that could explain why this detail is important for us to consider. And Jesus taught us the teacher must always be a learner. Your question indicates you are deeply studying! Good for you!
