- Some people believe that when a person's physical body perishes that he becomes an angel.Â
But angels are not glorified human beings. Matthew 22:30 explains that they do not marry or reproduce like humans, and Hebrews 12:22-23 says that when we get to the heavenly Jerusalem, we will be met by “myriads of angels†and “the spirits of righteous men made perfectâ€â€”two separate groups.
Angels are a company or association, not a race descended from a common ancestor (Luke 20:34-36). We are called “sons of men,†but angels are never called “sons of angels.â€
 In fact, God created the angels before he created the physical universe. In the book of Job, we read:Â
 “Where were you when I laid the earth's foundation? Tell me, if you understand. Who marked off its dimensions? Surely you know! Who stretched a measuring line across it? On what were its footings set, or who laid its cornerstone - while the morning stars sang together and all the angels shouted for joy?†(Job 38:4-7).
Notice the wording "ALL the angels shouted for joy." All the angels already existed at the time God created the world.Â
HOW DO ANGELS COMPARE TO HUMAN BEINGS?
- They are stronger than man, but not omnipotent (Psalm 103:20; 2 Peter 2:11).
- They are greater than man in knowledge, but not omniscient (2 Samuel 14:20; Matthew 24:36).
- They are more noble than man, but not omnipresent (Daniel 9:21-23, 10:10-14).
ARE ALL ANGELS GOOD?
Sorry! You can't trust every angel.
The Bible classifies some angels as “elect†(1 Timothy 5:21) or “holy†(Matthew 25:31; Mark 8:38). All angels were originally holy, enjoying the presence of God (Matthew 18:10) and the environment of heaven (Mark 13:32).
Other angels oppose God under the leadership of Satan (Matthew 25:41; 2 Peter 2:4; Jude 6; Ephesians 6:12). We often call these “demons.â€
There is actually a great unseen conflict raging that goes beyond anything we can imagine. It is not, however, a fight between two equal and eternal forces. God who created all beings is still in charge, and once He has used wicked angels to accomplish His purposes, He will bring them to a final defeat.
WHAT IS THE JOB DESCRIPTION FOR AN ANGEL?
We don't know whether every angel carries out the same tasks, or whether some of them specialize in certain areas. The Bible does speak about classes of angelic beings like cherubim (Ezekiel 1) and seraphim (Isaiah 6). We also know the names of two notable angels: Michael (Daniel 10:13; Jude 9) and Gabriel (Daniel 9:21; Luke 1:19,26).
The unnamed angels who appear most often in Scripture carry out a variety of tasks—all designed to serve God…
- Worship and praise - This is the main activity portrayed in heaven (Isaiah 6:1-3; Revelation 4-5).
- Revealing - They serve as messengers to communicate God's will to men. They helped reveal the law to Moses (Acts 7:52-53), and served as the carriers of much of the material in Daniel, and Revelation.
- Guiding - Angels gave instructions to Joseph about the birth of Jesus (Matthew 1-2), to the women at the tomb, to Philip (Acts 8:26), and to Cornelius (Acts 10:1-8).
- Providing - God has used angels to provide physical needs such as food for Hagar (Genesis 21:17-20), Elijah (1 Kings 19:6), and Christ after His temptation (Matthew 4:11).
- Protecting - Keeping God's people out of physical danger, as in the cases of Daniel and the lions, and his three friends in the fiery furnace (Daniel 3 and 6).
- Delivering - Getting God's people out of danger once they're in it. Angels released the apostles from prison in Acts 5, and repeated the process for Peter in Acts 12.
- Strengthening and encouraging - Angels strengthened Jesus after His temptation (Matt 4:11), encouraged the apostles to keep preaching after releasing them from prison (Acts 5:19-20), and told Paul that everyone on his ship would survive the impending shipwreck (Acts 27:23-25).
- Answering prayer - God often uses angels as His means of answering the prayers of His people (Daniel 9:20-24; 10:10-12; Acts 12:1-17).
- Caring for believers at the moment of death - In the story of Lazarus and the rich man, we read that angels carried the spirit of Lazarus to “Abraham's bosom†when he died (Luke 16:22).
