Angels are sons of God.
A son of God in Scripture one that was sinless in its creation. After the fall, the only way a man can become a son of God is through the new birth, by becoming a new creature in Christ, by believing in the d,b,r for sins.
I do not know where you get your info from.....however I sugest that the Bible be your 1st thing to rea because what you just posted is totally incorrect according to the Bible.
Having actually read the Bible I can tell you that the phrase "Sons of God" occurs ten times in the Bible. It occurs five times in the Old Testament (Genesis 6:2, 4; Job 1:6; 2:1; 38:7) and five times in the New Testament (Matthew 5:9; Luke 20:36; Romans 8:14, 19; Galatians 3:26).
The phrase has different meanings in the Old compared to the New Testament. LOCATION & CONTEXT!!!!
There were NO HUMANS in heaven in Job. In fact there are NO humans in heaven today. So, the sons of God can not be humans in Job. Job is thought to be the oldest book in the Bible and some say it predated Genesis.
Job 1:6.............
Now there was a day when the sons of God came to present themselves before the LORD,
and Satan also came among them.
Job 2:1.............
"Again there was a day when the sons of God came to present themselves before the LORD,
and Satan also came among them to present himself before the LORD."
In both passages Satan and the “sons of God” appear before the Lord. It is important to notice that the “sons of God” presented themselves before God. Therefore, since the holy angels in heaven are continually in the presence of God according to Matthew 18:10, the “sons of God” are not holy angels.
Instead they are the followers of Satan.
Jesus teaches us in Matthew 12:26 that Satan has his own kingdom. His followers are demons or angels who were cast out of heaven along with Satan. In Luke 10:18 Jesus states that He saw Satan cast out of heaven like lightning (Isaiah 14:15; Ezekiel 28:16-17). Revelation 12:9 helps us understand that some angels had joined Satan in his rebellion and were cast out of heaven too!
ONLY FALLEN ANGELS.....Demons would be associated with Satan and since there are NO humans in heaven the options are rather limited!
