For example, how an Angel of England might work to pursue the nation's destiny.
And, in this, how Not to fall-into physicsy ways of thinking about people en masse!
The first insight is that the destiny of a nation is not analogous to a blueprint, nor a plan; even though this is the first kind of metaphor that comes to my mind.
I want to avoid regarding the national angel as if part of a heavenly bureaucracy, 'tasked' with 'implementing' some particular aspect of the divine 'strategy', in-line-with God's mission statement.
So, if that is a wrong metaphor; then what would be better?
Well, some kind of family metaphor, obviously.
How could we, for instance, describe the way in which an 'ideal' father would act to pursue his family's destiny; especially the destiny of his children?
The ideal father would not be operating from plans or towards a blueprint; but instead from the fact of his being in harmonious accord with God's purposes and methods.
Then, whatever he actually did, would be in continuous interaction with the consequences of each individual child. For example, presumably each child would - from time to time, and indeed frequently - err and sin and start getting out-of-harmony with God.
The ideal father would perhaps remove positive incentives for his child to sin, keeping the child away from environments that endorse sin (beyond that child's capacity to discern and resist). He may actively try to dissuade wrong-directions and wrong-methods.
But whatever the ideal father did; each of his children would be unique, and would have his or her own unique destiny. The ideal father would try to work from-and-with each particular child's nature.
He would not try to force all of his children into one mould, nor even into a pre-planned unique mould that took no account of the child's choices; but the ideal father would be continually nurturing that child as he or she engaged with life in a trial and error fashion.
The ideal father would encourage what he hoped were the best choices, and work to make these choices available - but the child would decide. Bad choices by the child would lead to evil-inducing situation - that turned the child away from God.
The angel might try to 'engineer' or create situations in which the child might recognize and repent these bad choices and turn again towards God's creative intent.
But - to be effective - each 'engineered situation' ought to take account of the individual, and the situation in which he find's himself (the situation in-which he has, to some extent, placed himself).
The ideal father would then deal-with whatever choices the child had made; and work from wherever (whatever point) that choice had placed the child.
Then imagine that this ideal father was placed 'in charge' of a nation as the Angel of that nation; and was tasked with creating choices for individual persons and and dealing with the outcomes of those choices...
The angel takes into account the uniqueness of individual persons, and of spiritually-coherent and motivated groups of persons; but also the uniqueness of the individual nation of England.
The angel works much as the imagined ideal father; and therefore seeks to contribute to the alignment and harmony of the nation with on-going divine creation.
The angel of a nation would not ideally work alone, which would be ineffective; but would be helped greatly by dealing with other angels who had responsibility for various smaller groups.
Thus the angel of a nation would be analogous to an ideal tribal patriarch - a father-of-fathers; and angel-of-angels (or 'arch-angel').
But not by trying to force the nation to follow a pre-ordained path; rather, by knowing what is unique about that nation - nature, capabilities, motivations - and working with-and-from that.
Because nations are unique, none are 'equal' - except in the spiritual sense of being loved by God as his families. Some nations are better or worse than others, some more or less capable - and the national motivations vary in their Goodness and change in time, including as a consequence of earlier choices.
A once good and capable Nation may transform, through bad choices unrepeated, into an evil and/or inept nation; or a nation may break-up (or combine with another) for valid, or for evil, reasons.
(And, of course, some 'political units' that get called nations, are not coherent and destined 'spiritual-nations', and therefore lack a guarding and guiding angel. Such pseudo-nations (probably most of the nations of the world) properly, by God's intent, are under the responsibility of another nation's angel; or else the people ought to disperse to other real nations.)
Throughout, the angel continues to work with the nation - starting from wherever the nation actually is; and with short term aims that are varied in accordance with the consequences of choices. What might be a good choice for a good nation, may become an evil choice for a bad nation.
The national angel needs continually to take account of what he is dealing-with here-and-now, and how best to encourage that national being to become its best possible self; how to develop the best possible family environment for nurturing God's children; and how that nation (as it is, as it could become) may optimally contribute to God's ongoing creation.
Note: My assumption is that angels are either male or female, men or women; and therefore it seems likely that some nations have a father/ patriarch archangel, while others have a mother/ matriarch archangel. Furthermore, this makes-a-difference; since men and women differ. Alternatively, or instead, it may be that nations are ruled by both a man and women angel united in eternal marriage as a dyad - in the same way as 'God'. Therefore, the 'ideal father' in the above passages may be changed to 'ideal mother' - mutatis mutandis.
