The angels are not subject to salvation. The commandment "ye must be born again "does not apply to them
Hebrews 2:5 For unto the angels hath he not put in subjection the world to come, whereof we speak.
That which is born of the flesh is flesh; and that which is born of the Spirit is spirit. Marvel not that I said unto thee, Ye must be born again. Joh 3:6
Genesis 1:22 And God blessed them, saying, Be fruitful, and multiply, and fill the waters in the seas, and let fowl multiply in the earth.
No multiplying of lying spirits (1/3 of all the angels that fell.)
Therefore in the resurrection whose wife shall she be of the seven? for they all had her. Jesus answered and said unto them, Ye do err, not knowing the scriptures, nor the power of God.For in the resurrection they neither marry, nor are given in marriage, but are as the angels of God in heaven.But as touching the resurrection of the dead, have ye not read that which was spoken unto you by God, saying,I am the God of Abraham, and the God of Isaac, and the God of Jacob? God is not the God of the dead, but of the living.And when the multitude heard this, they were astonished at his doctrine. Mathew 22:28
Mark 12:25 For when they shall rise from the dead, they neither marry, nor are given in marriage; but are as the angels which are in heaven.
Hebrews 2:16 For verily he took not on him the nature of angels; but he took on him the seed of Abraham.
No seed of angels.
