The physical description of Angels is limited, the details of their activities are also limited. Angels are personal spiritual beings who have intelligence, emotions, and will. This is true of both the good and evil angels (demons). Angels fall into two categories: the "unfallen" angels and the fallen angels. Unfallen angels are those who have remained holy throughout their existence and accordingly are called "holy angels." In Scripture, generally when angels are mentioned, it is the class of holy angels in view. By contrast, the fallen angels are those who have not maintained their holiness. Angels possess intelligence (Matthew 8:29; 2 Corinthians 11:3; 1 Peter 1:12), show emotion (Luke 2:13; James 2:19; Revelation 12:17), and exercise will (Luke 8:28-31; 2 Timothy 2:26; Jude 6). Angels are spirit beings (Hebrews 1:14) without true physical bodies. Although they do not have physical bodies, they are still personalities.
Because they are created beings, their knowledge is limited. This means they do not know all things as God does (Matthew 24:36). They do have greater knowledge than humans and don not suffer from memory problems, however, this may be due to three things. First, angels were created as an order of creatures higher than humans. Therefore, they innately possess greater knowledge. Second, angels were present when the Holy Spirit spoke the actual words of God to man and they gain knowledge from it (James 2:19; Revelation 12:12). Third, angels gain knowledge through long observation of human activities. Unlike humans, angels do not have to study the past; they have experienced it. Therefore, they know how others have acted and reacted in situations and can predict with a greater degree of accuracy how we may act in similar circumstances.
Though they have wills, angels, like all creatures, are subject to the will of God. Good angels are sent by God to help believers (Hebrews 1:14).
Most holy angels are not named in the Bible but are described only as "elect angels" (1 Timothy 5:21). The expressions "principalities" and "powers" is used of all angels whether fallen or holy (Luke 21:26; Romans 8:38; Ephesians 1:21; 3:10; Colossians 1:16; 2:10, 15; 1 Peter 3:22). Some angels are designated as "Cherubim," which are living creatures who defend God's holiness from any defilement of sin (Genesis 3:24; Exodus 25:18, 20, Ezekiel 1:1-13).
The seraphim (fiery, burning ones) are angelic beings associated with the prophet Isaiah's vision of God in the Temple when God called him to his prophetic ministry (Isaiah 6:1-7).
“Above it stood the seraphims: each one had six wings; with twain he covered his face, and with twain he covered his feet, and with twain he did fly. And one cried unto another, and said, Holy, holy, holy, is the Lord of hosts: the whole earth is full of his glory. And the posts of the door moved at the voice of him that cried, and the house was filled with smoke.”
Seraphs are angels who worship God continually.” Isaiah 6:2-4
Isaiah chapter 6 is the only place in the Bible that specifically mentions the Seraphim. Each seraph had six wings. They used two to fly, two to cover their feet, and two to cover their faces (Isaiah 6:2). The seraphim flew about the throne on which God was seated, singing His praises as they called special attention to God’s glory and majesty. These beings also served as agents of purification for Isaiah as he began his prophetic ministry. One placed a hot coal against Isaiah's lips with the words, “See, this has touched your lips; your guilt is taken away and your sin atoned for” (Isaiah 6:7). Similar to the other types of holy angels, the seraphim are perfectly obedient to God. Similar to the cherubim, the seraphim are particularly focused on worshipping God.
Ezekiel’s vision of the four wheels dramatically illustrates the omnipresence and omniscience of God. These wheels were associated with the “Cherubim, four living creatures” (Ezekiel 1:15–20), who were later described (Ezekiel 10:5, 20) as cherubim, angelic beings appointed as guardians of the holiness of God.
Each wheel was actually two in one, with one set inside the other at right angles which enabled the “living creatures” to move in any direction instantly without having to turn, like a flash of lightning. These wheels had the appearance of chrysolite, which appears as topaz or some other semiprecious stone. The outer rim of the wheels was described as high and awesome with the outer edge of the rims inset with “eyes” (Ezekiel 1:14-18).
The Spirit of the living creatures was in the wheels (Ezekiel 1:20-21). As a result, the creatures were able to move any direction the wheels moved. The Spirit of God gives direction to the wheels through direct knowledge of and access to the will of God. The mobility of the wheels suggests the omnipresence of God; the eyes, His omniscience; and the elevated position, His omnipotence.
It presented God as being on a chariot-like throne, His glory both supreme and immanent, existing in and extending into all the created universe. As such, the whole revelation by God in this vision to Ezekiel, i.e., the cherubim, the chariot, the Spirit, and the wheels, emphasized their unity and coordination.
The word archangel occurs in only two verses of the Bible. “For the Lord himself shall descend from heaven with a shout, with the voice of the archangel, and with the trump of God: and the dead in Christ shall rise first:” 1 Thessalonians 4:16
The other passage is “Yet Michael the archangel, when contending with the devil he disputed about the body of Moses, durst not bring against him a railing accusation, but said, The Lord rebuke thee.” Jude 9
Michael is the only named archangel in the Biblical Scripture.
The word archangel comes from a Greek word, archangelos, meaning “chief angel.” It’s a compound word formed from archon (“chief” or “ruler”) and aggelos (“angel” or “messenger”). The Bible suggests in several places that angels have a hierarchy of leadership, and an archangel is the leader of other angels.
Like all angels, archangels are personal beings created by God. They possess intelligence, power, and glory. They are spiritual in nature, rather than corporeal. Archangels serve God and carry out His purposes.
Jude 1:9 uses the definite article the when referring to the archangel Michael, which indicate that Michael is the only archangel. However, Daniel 10:13 describes Michael as “one of the chief princes.” Indicating that there are more than one archangel, because it places Michael on the same level as the other “chief princes.” The book of Enoch describes seven archangels with Michael being the chief among them.
In Daniel 10:21 an angel describes Michael the archangel as “your prince.” Since the angel is speaking to Daniel, and since Daniel is a Jew, we take the angel’s statement to mean that Michael is charged with overseeing the Jewish people. Daniel 12:1confirms this interpretation, calling Michael “And at that time shall Michael stand up, the great prince which standeth for the children of thy (Daniel’s) people:”
Other archangels are given the task of protecting other nations, but Scripture does not identify them. Fallen angels have “territories” as well, as Daniel mentions a spiritual “prince of Greece” and a spiritual “prince of Persia” who oppose the holy angel who brought the message to Daniel (Daniel 10:20).
One of the duties of an archangel, as seen in Daniel 10, is to engage in spiritual warfare. In 1 Thessalonians 4, the archangel is involved in the return of Christ for His church. We also see Michael the archangel contending with Satan in Jude 1:9. Even possessing the power and glory of an archangel, Michael called on the Lord to rebuke Satan. This shows how powerful Satan is, as well as how dependent Michael is on God’s power.
Most of the references to holy angels in Scripture refer to their ministries, which are broad. Holy angels were present at creation, the giving of the Law, the birth of Christ and His resurrection, the Ascension, and they will be present at the rapture of the Church and the second coming of Christ.
In stark contrast to the company of holy angels, the fallen angels are also innumerable, though considerably less than the holy angels, and are described as fallen from their first estate. Led by Satan, who was originally a cherub, the fallen angels defected, rebelled against God, and became sinful in their nature and work. Fallen angels have been divided into two classes: those who are free and those who are bound. Of the fallen angels, Satan alone is given particular mention in the Bible. When Satan fell (John 8:44; Luke 10:18), he drew after him one third of the angels. Of those, some are reserved in chains awaiting judgment (1 Corinthians 6:3; 2 Peter 2:4; Jude 1:6), and the remainder are free and are the demons, or devils, to whom reference is made throughout the New Testament (Mark 5:9, 15; Luke 8:30; 1 Timothy 4:1). They are Satan's servants in all his undertakings and share his doom (Matthew 25:41; Revelation 20:10).
They praise God (Psalm 148:1-2; Isaiah 6:3). They worship God (Hebrews 1:6; Revelation 5:8-13). They rejoice in what God does (Job 38:6-7). They serve God (Psalm 103:20; Revelation 22:9). They appear before God (Job 1:6; 2:1). They are instruments of God's judgments (Revelation 7:1; 8:2). They bring answers to prayer (Acts 12:5-10). They aid in winning people to Christ (Acts 8:26; 10:3). They observe Christian order, work, and suffering (1 Corinthians 4:9; 11:10; Ephesians 3:10; 1 Peter 1:12). They encourage in times of danger (Acts 27:23-24). They care for the righteous at the time of death (Luke 16:22). Overall, the work of angels on this planet is not completely known, their work is vast and is beyond this planet and expands into the universe with all of Gods other creations. What man knows about angels is infinitesimal, regardless of the thousands of years they have been written about and the reported encounter over the millennia.
Angels are an entirely different order of being than humans. Human beings do not become angels after they die. Angels will never become, and never were, human beings. God created the angels, just as He created humanity. The Bible nowhere states that angels are created in the image and likeness of God, as humans are (Genesis 1:26). Angels are spiritual beings that can, to a certain degree, take on physical form. Humans are primarily physical beings, but with a spiritual aspect. The greatest thing we can learn from the holy angels is their instant, unquestioning obedience to God’s commands.
