Yes, God has chosen to step inside the bubble as The Word made flesh Who dwelt among us. And yes, even spirits will have some where/when 'arrangement' since they are also created 'things'. So the seeming paradox becomes, God is non-local because He exists outside the bubble of spacetime which He created, but God is also 'all-local' as His Spirit sustains the extremely delicate balance of it all, and as He has chosen to take flesh and dwell among us.
[Shhhh, whatever you do, don't show this to certain geniuses wishing to diminish God rather than exalt God.]
Indeed, dear MHGinTN the creation seems not to have been a "one-shot deal," rather it is a continuous activity, from Alpha to Omega.... That is to say, timeless (i.e., eternal) God works in time.... There's a paradox here from the human standpoint; but it does not apply to God or limit Him in any way. For as you say, He is at once non-local and all-local.
Thank you so very much for your wonderful insights, dear brother in Christ!
It is a very interesting meditation.
