What remain constant in every account of angels, from ancient days to the present, is that they are both messengers and companions to humans, sent from a realm beyond usual seeing. Angels appear, and in one way or another, help us, advise us, inspire us, or amaze us.
In all our activities we may be seeking God: in our work, on our social occasions, as we walk along the road, even when we are so busy that we have not time to think of anything except what we are doing... God can deal with us under a thousand forms for our spiritual hallowing. Behind all the strange puzzles of life there is the secret working of God, creating life, creating character, accepting service -- all sorts of spiritual shaping going on.
