An angel(from the Greek word "angelos") means messenger.Angels in the bible apply to to heavenly beings,a pure spirit created by God,who act as messengers between Heaven and Earth.They are supposed to be guardian spirits..who have no physical bodies but when they do appear they appear in the form of men.Gen18.They are mentioned at least 108 times in the Old Testament and 165 times in the New Testament.However,not all angels are good-there are angels who are against God and work under the leadership of Satan...they are the demonic angels.
I believe in angels as I am Christian. One could be with you right now but you wouldn't know it since you can only see them if the angel want you to see them. Angels were created by God a long while back and they all have different jobs. They are in spirit form so I image them as a huge yellow or purple blob of light, hah, but they can shift themselves into human form. But if people call you an angel it means a nice, pleasant person.
Real? yes. Beside us? Not necessarily. Angels are created heavenly beings that act as messengers and occasionally guardians for God. (They guard us occasiinally not God). I doubt seriously we have a personal angel attached to us. The whole personal 'guardian angel' thing is a story for children. God is perfectly capable of guarding us on His own. But He uses the angels sometimes as well. Almost everything youve seen or heard about angels is probably false outside what the Bible says. The catholic church especially has made up all sorts of fantasies about angels and demons both - ranks, jobs, hierarchies, names, all sorts of foolishness that has absolutely nothing to do with anything God has said. Hollywood (film industry) has made up a lot of false stuff too.
NO evidence of such being as "angel" has as yet been offered. So far, these are vagaries of delusional mind and children of credulous imagination; these are but phantoms of aristocratic "nothing", and eternal procession of "agitated air" - that ignorance invented, impostors established, and hypocritical interest preserves. Angels and demons occupy the same relations in the realm of the unprejudiced minds as unicorns or ghosts or goblins does. There is nothing supernatural about this universe.
Having no conception of the supernatural I would not know an Angel even if I should see one, and no honest man can but confess the same. And those who claim otherwise, are either deceived, or deceiving others, or, at best, honestly mistaken.
Angels are spiritual beings created by God. They are messengers, warriors, and worshippers of God. Some angels rebelled against God, once with their leader Lucifer aka Satan and the second time was around the time of the Noah story before the great flood.
