While angels are called "sons of God" in Scripture, there are no verses that speak of them being "born again", or "regenerated", or have become "new creatures". That is the sense in which I was speaking.
Consider 1 Jn 3:9 - Whosoever is born of God doth not commit sin; for his seed remaineth in him: and he cannot sin, because he is born of God.
Is this verse saying that believers cannot sin? Of course not. It is speaking of the regenerated human spirit (born of God), and that when the believer functions from the human spirit, he cannot sin. IOW, when functioning from the human spirit, where the Holy Spirit resides, the believer is being "filled with the Spirit" (Eph 5:18) and is "walking by means of the Spirit" (Gal 5:16). In that state, the believer cannot grieve the Spirit (Eph 4:30) nor quench the Spirit (1 Thess 5:19).
When believers allow the Holy Spirit to guide them, they cannot sin. It is only when believers are grieving or quenching the Spirit are they sinning.
Angels don't need to be born again if they are sons of God, sir!
We are born again, which is a reference to being "born of God", ie; sons of God.
Whoever believes that Jesus is the Christ
is born of God, and everyone who loves Him who begot also loves him who is begotten of Him.
1 John 5:1
We are sons of God through faith in Christ, now.
We will receive the full reality of sonship at the resurrection, which is the redemption of our body, in addition to the full measure of the Spirit.
Then we will be equal to the angels, being fully declared as sons of God in reality!
35 But those who are counted worthy to attain that age, and the resurrection from the dead, neither marry nor are given in marriage; 36 nor can they die anymore,
for they are equal to the angels and are sons of God, being sons of the resurrection.
Luke 20:35-36
John says it this way -
Beloved, now we are children of God; and
it has not yet been revealed what we shall be, but we know that when He is revealed,
we shall be like Him, for we shall see Him as He is. 1 John 3:2 NKJV
The point that I am making is this: angelic beings that are sons of God, or human beings that are sons of God, are in fact SONS OF GOD.
Adam was declared to be the son of God.
Adam was created directly by God.
The angels (sons of God) that sinned, were cast down to hell.
These were not "tares", but sons of God, angels who sinned.
Peter is writing a warning to the Church, to saved people, when he writes these words and shows
the punishment of the angels and the people Who live ungodly.
For if God did not spare the angels who sinned, but cast them down to hell and delivered them into chains of darkness, to be reserved for judgment; 5 and did not spare the ancient world, but saved Noah, one of eight people, a preacher of righteousness, bringing in the flood on the world of the ungodly; 6 and turning the cities of Sodom and Gomorrah into ashes, condemned them to destruction,
making them an example to those who afterward would live ungodly;
2 Peter 2:4-6
And again -
And the angels who did not keep their proper domain, but left their own abode, He has reserved in everlasting chains under darkness for the judgment of the great day; 7 as Sodom and Gomorrah, and the cities around them in a similar manner to these,
having given themselves over to sexual immorality and gone after strange flesh, are set forth as an example, suffering the vengeance of eternal fire. Jude 6-7 NKJV.
