My peace I give to you. Not as the world gives do I give to you. Let not your hearts be troubled, neither let them be afraid.
~ John 14:22
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.
