Angelic beings have always been a mystery to human beings, but the Bible reveals the existence of these invisible and spirit beings. They were created to be messengers, ministers, and helpers to God's human children: "For he shall give his angels charge over thee, to keep thee in all thy ways" (Psalm 91:11). Apparently, when these angelic beings manifest themselves to human beings, they do so in the form of men.
Demon-angels also appear frequently , comparatively or not, to men, women and children, as if "angels of light" - including or also as if Jesus or mary worldwide - only to deceive whole populations, billions of people , as the Creator permits.
