We are informed in Scripture as to the number, and the power and glory, of the heavenly beings, of their connection with the government of God, and also of their relation to the work of redemption.... In the presence-chamber of the King of kings they wait—“angels, that excel in strength,” “ministers of His, that do His pleasure,” “hearkening unto the voice of His word.” Ten thousand times ten thousand and thousands of thousands, were the heavenly messengers beheld by the prophet Daniel....
A guardian angel is appointed to every follower of Christ. These heavenly watchers shield the righteous from the power of the wicked one. This Satan himself recognized when he said, “Doth Job fear for naught? Hast not Thou made a hedge about him, and about his house, and about all that he hath on every side?” ... Said the Saviour, speaking of those that believe in Him, “Take heed that ye despise not one of these little ones; for I say unto you, That in heaven their angels do always behold the face of My Father.” The angels appointed to minister to the children of God have at all times access to His presence. Thus God’s people, exposed to the deceptive power and unsleeping malice of the prince of darkness ... are assured of the unceasing guardianship of heavenly angels.... If God has granted to His children promise of grace and protection, it is because there are mighty agencies of evil to be met—agencies numerous, determined, and untiring, of whose malignity and power none can safely be ignorant or unheeding.—The Great Controversy, 511-513.

While these words of holy trust ascend to God, the clouds sweep back, and the starry heavens are seen, unspeakably glorious in contrast with the black and angry firmament on either side. The glory of heaven is beaming from the gates ajar. Then there appears against the sky a hand holding two tables of stone folded together. The hand opens the tables, and there are revealed the precepts of the decalogue, traced as with a pen of fire. The words are so plain that all can read them. Memory is aroused, the darkness of superstition and heresy is swept from every mind, and God's ten words, brief, comprehensive, and authoritative, are presented to the view of all the inhabitants of earth. Wonderful code! wonderful occasion!—The Spirit of Prophecy 4:456-457. Hvn 29
But ye are come unto
mount Sion, and unto the city of the living God, the heavenly Jerusalem,
and to an innumerable company of angels. Hebrews 12:22. KJV
