dr. billy graham discusses the reality of angels in his second chapter. he points out that “angels belong to a uniquely different dimension of creation that we, limited to the natural order [four dimensions], can scarcely comprehend. . . . he has given angels higher knowledge, power and mobility than we. . . . they are god’s messengers whose chief business is to carry out his orders in the world. . . . he has designated and empowered them as holy deputies to perform works of righteousness. . . . angels are nonmaterial; hebrews 1:14 calls them ministering ‘spirits.’ intrinsically, they do not possess physical bodies, although they may take on physical bodies when god appoints them to special tasks.”
