I‘m saying that what is now fallen will be restored to perfection and will remain that way forever.
You believe in universalism?
Claiming all that has fallen will be made right, and even satan and his demons will be restored to fellowship with God?
Do you not embrace Acts 3:21?
Acts 3:21
Whom the heaven must receive until the times of restitution of all things, which God hath spoken by the mouth of all his holy prophets since the world began.
That's referring to the Lord coming back unto absolute control of all of His creation after this age we are in now
You must have forgotten that the Lord gave man dominion over the earth in Genesis which is why the world is in darkness now.
We see in the Book of Hebrews that Jesus has not assumed full control over this world yet:
Hebrews 2:8
Thou hast put all things in subjection under His feet. for in that
He put all in subjection under Him, He left nothing that is not put
under Him. But now we see not yet all things put under Him
And, we also see that the devil is called the god of this world which
will not change until Jesus returns to start His 1000 year reign and
throws the devil and his demons in to hell.
2 Corinthians 4:4
In whom the god of this world hath blinded the minds of them which
believe not, lest the light of the glorious gospel of Christ, who
is the image of God, should shine unto them.
Jesus speaking of the devil, says he is the prince of this world.
John 14:30
the prince of this world cometh, and hath nothing in me.
And we see that the last enemy put under foot is death which has not happened as of yet.
1 Corinthians 15:26
The last enemy that shall be destroyed is death.
