"When the time for the Savior's advent was at hand, an angel was sent to announce to Mary that she was to be the mother of the Son of God. Then a host of angels was commissioned to sing on the night the baby Jesus was born. Shortly thereafter an angel would announce to Joseph that the newborn baby was in danger and this little family must flee to Egypt for safety. When it was safe to return, an angel conveyed that information to the family and the three returned to the land of their heritage."From the beginning down through the dispensations, God has used angels as His emissaries in conveying love and concern for His children. . . ."Usually such beings are not seen. Sometimes they are. But seen or unseen they are always near. Sometimes their assignments are very grand and have significance for the whole world. Sometimes the messages are more private. Occasionally the angelic purpose is to warn. But most often it is to comfort, to provide some form of merciful attention, guidance in difficult times."
