Do angels really exist? According to the Bible they do. Angels are messengers, they can be good or bad, and they are assigned to serve humans. Eye-witness accounts of angel visits and interventions permeate history, and many stories have told how a stranger who provided aid simply just disappeared--lending weight to the familiar phrase "entertaining angels unaware."
Many of the great master painters focused on depicting angels in their art masterpieces. Raffaello and Botticelli are two of the most notable.
