The Father wrought by His Son in the creation of all heavenly beings. “By Him were all things created, ... whether they be thrones, or dominions, or principalities, or powers; all things were created by Him, and for Him.”—Patriarchs and Prophets, 34. TA 25.3
Before the creation of man, angels were in existence; for when the foundations of the earth were laid, “the morning stars sang together, and all the sons of God shouted for joy.” Job 38:7. After the fall of man, angels were sent to guard the tree of life, and this before a human being had died. Angels are in nature superior to men, for the psalmist says that man was made “a little lower than the angels.” Psalm 8:5.—The Great Controversy, 511. TA 25.4
From eternal ages it was God's purpose that every created being, from the bright and holy seraph to man, should be a temple for the indwelling of the Creator.—The Desire of Ages, 161. TA 26.1
All created beings live by the will and power of God. They are dependent recipients of the life of God. From the highest seraph to the humblest animate being, all are replenished from the Source of life.—The Desire of Ages, 785. TA 26.2
When the Lord created these [angelic] beings to stand before His throne, they were beautiful and glorious. Their loveliness and holiness were equal to their exalted station. They were enriched by the wisdom of God, and girded with the panoply of heaven.—The Signs of the Times, April 14, 1898. TA 26.3
