And when the Redeemer first came into this lower world, and thereby a work, more glorious than that of creation, was begun by him, they celebrated his birth with a triumphant song; as it is said, that with the angel that brought the tidings thereof to the shepherds, there was a _multitude of the heavenly host praising God, and saying, Glory to God in the highest; on earth peace; good will towards men,_ Luke ii. 14. Whether all the hosts of heaven were present at that solemnity, we know not; but there is sufficient ground to conclude, from the harmony that there is in the work and worship of the heavenly inhabitants, that they all celebrated his incarnation with their praises; and this was a part of that worship, which, upon this great occasion, they gave, by a divine warrant, to him, who was then brought into this lower world, Heb. i. 6. Moreover, they praise God for particular mercies vouchsafed to the church, and for the success of the gospel in the conversion of sinners thereby; on which occasion, they express their joy as our Saviour observes, though it be but _one sinner that repenteth_, Luke xv. 7, 10. And, _Lastly_, They are represented, as joining in worship with the saints in heaven; for which reason the apostle, speaking concerning the communion that there is between the upper and the lower world, as well as the union between the saints departed, and the angels, in this work of praise, says, _Ye are come unto the innumerable company of angels, to the general assembly and church of the first-born, which are written in heaven, and to the spirits of just men made perfect,_ Heb. xii. 22, 23. and they are also represented as joining with all others, which are _before the throne, the number of whom is ten thousand times ten thousand, and thousands of thousands, saying, with a loud voice, Worthy is the Lamb that was slain, to receive power, and riches, and wisdom, and strength, and honour, and glory, and blessing,_ Rev. v. 11, 12.
