The angels honour and serve Christ

It was the joy of the angels of heaven to be subject and serviceable unto Jesus Christ.
(i.) Before the incarnation of Christ, an angel instructed Daniel concerning the Messiah, and how long it should be before his coming. (Dan. 9:24, 25.)
(ii.) When the fulness of time was come, an angel comes to the blessed virgin, and said, “Fear not, Mary: for thou hast found favour with God. And, behold, thou shalt conceive in thy womb, and bring forth a son, and shalt call his name Jesus.” (Luke 1:30, 31.)
(iii.) As soon as ever he was born, an angel brings the glad tidings of it; and a whole “host” of them who “sang together and shouted for joy” at the creation of the world, (Job 38:7,) do with a song celebrate Christ’s nativity: “Glory to God in the highest, and on earth peace, good-will toward men.” (Luke 2:13, 14.)
(iv.) When Jesus Christ was in danger to be killed by Herod, an angel warns of the danger, and directs his mother to flee with him into Egypt. (Matt. 2:13.)
(v.) When he was tempted by Satan forty days together, a little before he entered upon the work of his ministry, “behold, angels came and ministered unto him.” (Matt. 4:11.)
(vi.) When he was in his agony in the garden, ready to take the cup of trembling out of his Father’s hand, “there appeared an angel from heaven strengthening him.” (Luke 22:43.) This blessed creature, out of love and duty, seeing his Lord and Master in such distress, came-in to succour him.
(vii.) And as the angels gave the first notice of his birth, so also of his resurrection: an angel told the women, “He is not here: for he is risen.” (Matt. 28:6.)
(viii.) The angels attended Christ’s ascension into heaven, for they told the disciples, that as they saw him ascending into heaven, so he should come again from heaven in like manner. (Acts 1:11.)
(ix.) And with infinite delight did they welcome Christ to heaven, where, upon his first coming, “all the angels did worship him.” (Heb. 1:6.)
(x.) And lastly: when Christ shall come at the last day to judge both quick and dead, he will come with all his “holy angels with him,” (Matt. 25:31,) and “shall be revealed from heaven with his mighty angels;” (2 Thess. 1:7;) who then most willingly will be employed to “gather together all his elect from the four winds of heaven.” (Matt. 24:31.)
All this service the good angels perform unto Christ, not only as he is their Creator: (“for by him were created” even the “things that are in heaven;” Col. 1:16;) but they yield him this subjection as he is their Head and Governor. And so he is called “the Head of all principality and power;” (Col. 2:10; Eph. 1:21, 22;) that is, of angels.
