Col. 1:16--"For by him were all things created, that are in heaven, and that are in earth, visible and invisible, whether they be thrones, or dominions, or principalities, or powers; all things were created by him, and for him." Angels are not the spirits of the departed, nor are they glorified human beings (Heb. 12:22, 23). Neh. 9:6--"Thou, even thou, art Lord alone; thou hast made heaven, the heaven of heavens, with all their host." 2. THEY ARE SPIRITUAL BEINGS. Heb. 1:14--"Are they not all ministering spirits?" Psa. 104:4--"Who maketh his angels spirits; his ministers a flaming fire." It is thought by some that God creates angels for a certain purpose, and when that purpose is accomplished they pass out of existence. But that there are many, many angels in existence all the time is clear from the teaching of the Scriptures. Although the angels are "spirits," they nevertheless oft-times have appeared to men in visible, and even human form (Gen. 19; Judges 2:1; 6:11-22; Matt. 1:20; Luke 1:26; John 20:12). There seems to be no sex among the angels, although wherever the word "angel" is used in the Scriptures it is always in the masculine form. 3. THEY ARE BEINGS OF GREAT MIGHT AND POWER. 2 Pet, 2:11--"Whereas angels, which are greater in power and might (than man)." Psa. 103:20--"Angels that excel in strength." One angel was able to destroy Sodom and Gomorrah, and other guilty cities; one angel smote the first-born, and rolled away the great stone from the mouth of the tomb. One angel had power to lay hold of that old dragon, the devil (Rev. 20:2, 10); one angel smote a hundred and fourscore and five thousand Assyrians (Isa. 37:36). Their power is delegated; they are the angels of _His_ might (2 Thess. 1:7), the ministers through whom God's might is manifested. They are mighty, but not almighty. 4. THERE ARE VARIOUS RANKS AND ORDERS OF ANGELS. We read of Michael, the archangel (Jude 9; 1 Thess. 4:16); angels, authorities, and powers--which are supposedly ranks and orders of angels (1 Pet. 3:22; Col. 1:16). In the Apocryphal books we find a hierarchy with seven archangels, including Michael, Gabriel, Raphael, Uriel. The fact that but one archangel is mentioned in the Scriptures proves that its doctrine of angels was not derived, as some supposed, from Babylonian and Persian sources, for there we find seven archangels instead of one. 5. THE NUMBER OF ANGELS. Heb. 12:22, R. V.--"Innumerable hosts of angels." Cf. 2 Kings 6:17; Matt. 26:53; Job 25:3. III. THE FALL OF ANGELS. Originally all angels were created good. The Scriptures speak of a fall of angels--"the angels that sinned." 2 Pet. 2:4--"For if God spared not the angels that sinned, but cast them down to hell, and delivered them into chains of darkness, to be reserved unto judgment." Jude 6--"And the angels which kept not their first estate, but left their own habitation, he hath reserved in everlasting chains under darkness unto the judgment of the great day."
