"Despite their spirit nature, not even angels were created immortal.
This is shown by the fact that those spirit creatures who joined Satan’s rebellion will be executed. (Matthew 25:41)"
That is an assumption mrgordon,because the unfallen angels are not subject to time death etc because death is a only an enemy here on this earth because of sin 1corinthians 15.26
The unfallen angels live where there is no sin,and thus the are in perfect harmony with their creator,there is no death or dying in heaven,their father sustains them and they are willingly subordinate to him
God created every being with freedom of choice,lucifer and his minions exercised his freedom of choice to become seperate from God,he said "i will become like the most high"
It is a natural state of being for unfallen beings to have their existence subordinate to gods spirit and therefore be eternal there is no reason for their existence to be finite
Lucifers own choice will have his existence cut off,because that is what he has chosen
"And the angels which kept not their first estate, but left their own habitation, he hath reserved in everlasting chains under darkness unto the judgment of the great day."
When Gods mercy is withdrawn from this universe,which is not the way God intended to be,when he withdraws his spirit from this universe,not because he wants to,but because noone wants him anymore,he will withdraw and the divine spirit of god on which all of nature relies to uphold it,will collapse on itself like at the time when God withdrew from the antideluvian world when he was no longer wanted,and lucifer/satan and his angels will become subject to death by their own choice of rejecting Gods spirit from their own existence,and therefore will be subject to the 2nd death,which is death eternal
Jesus said choose me,or choose death
In other words,accept my spirit or go your own way(carnal spirit) and die,where there is no gods spirit,there can be no life,his angels own choice,its what they chose
