Question: "What does the Bible say about angels?"
Answer: Angels are personal spiritual beings, having aspects of intelligence, emotions, and will. This is true of both the good and evil angels. Angels possess intelligence (Matthew 8:29; 2 Corinthians 11:3; 1 Peter 1:12), show emotions (Luke 2:13; James 2:19; Revelation 12:17), and demonstrate that they have wills (Luke 8:28-31: 2 Timothy 2:26; Jude 6). Angels are spirit beings (Hebrews 1:14), with no true physical body. The fact that they do not have bodies does not affect their being personalities (any more than it does with God).
The knowledge angels possess is limited by their being created beings. This means they do not know all things as God does (Matthew 24:36). They do seem to have greater knowledge than humans, however. This may be due to three causes. (1) Angels were created as a higher order of creatures in the universe than humans are. Therefore, innately they possess greater knowledge. (2) Angels study the Bible and the world more thoroughly than humans do and gain knowledge from it (James 2:19; Revelation 12:12). (3) 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, the angels are, like all creatures, subject to the will of God. Good angels are sent by God to help believers (Hebrews 1:14). Here are some activities the Bible ascribes to angels:
A. They praise God (Psalm 148:1,2; Isaiah 6:3).
B. They worship God (Hebrews 1:6; Revelation 5:8-13).
C. They rejoice in what God does (Job 38:6-7).
D. They serve God (Psalm 103:20; Revelation 22:9).
E. They appear before God (Job 1:6; 2:1).
F. They are instruments of God's judgments (Revelation 7:1; 8:2).
G. They bring answers to prayer (Acts 12:5-10).
H. They aid in winning people to Christ (Acts 8:26; 10:3).
I. They observe Christian order, work, and suffering (1 Corinthians 4:9; 11:10; Ephesians 3:10; 1 Peter 1:12).
J. They encourage in times of danger (Acts 27:23,24).
K. They care for the righteous at the time of death (Luke 16:22).
Angels are an entirely different order of being from 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 angels is their instant, unquestioning obedience to Godís commands.
