Angels, as "_spirits_," are immortal, and hence will live forever. And thus also our own spirits must live forever, because derived from the _spirit-life_ of God. Revelations furnish us abundant evidence of the _spirit_ nature of angels. They were oft present and speaking with the prophets, and were yet _invisible_, as also within doors where locks and bars precluded the possibility of substance, or of earth-life animation entering. And yet again, we have evidence of their appearing in tangible form, and could be seen, and felt, and we read of their being "entertained as men unawares." When, however, they appeared as _angels_, we learn that their bodily aspect was that of transcendent beauty; their face and form resplendent with light, and a halo, as of Divinity itself, shone around them. It seems that angels have ever manifested a deep and abiding interest in behalf of our Earth, and of man. We are told that they celebrated the creation of this world "with songs of praise and shouts of joy." At the time of the birth of the Saviour, an angel from God appeared to the shepherds, who were watching their flocks by night, and announced the "glad tidings of great joy, and immediately there appeared with the angel, a multitude of the heavenly hosts" sounding loud the anthem of praise, "Glory to God in the highest, peace on Earth and good-will to men." How strange this incident! The tongues of men were silent in this the hour of dawn of their redemption, and the angels alone heralded the event, and sang the anthem of praise. An angel subsequently warned Joseph to seek a place of safety for the "Infant of days," as "Herod, the King, would seek to destroy the young child's life." During the Saviour's sojourn on Earth, how oft did angels appear and minister unto Him; even "strengthening Him," when His human nature staggered under the load of the sins of a guilty world. And when--seemingly--the "star of Bethlehem" had set, and the hope of the world seemed lost; when the promised Messiah was entombed; when dismay seized upon, and thick darkness shrouded the minds of all who had followed the Saviour; when even the Marys who loved Him, repaired at early dawn to shed their tears at His sepulchre: Behold! "_The angel of the Lord was there_;" had "rolled away the stone and sat upon it." He did not need to inquire their errand, but said unto them: "I know it is Jesus whom ye seek, he is not here, for He is risen." Oh, see what interest the angels have ever manifested in our behalf! "_Are they not all ministering spirits, sent forth to minister unto those who shall be the heirs of salvation?_" THE VAST NUMBER OF THE ANGELS. "_An innumerable company of angels._" Heb. xii. 22.
