Why do angels like disguise? They come as visions, vices, dreams, coincidences, and intuition, the whisper of knowledge at your ear. They come as animals or other people, or as a wash of peace in an ailing heart. Sometimes a stranger may come up and give you just the information or assistance you need. Sometimes you yourself are used as an angel, for a moment, either knowingly or not, speaking words you did not know you knew.
