Never would call Jesus a liar. I am saying other things.

Matt 25:41 seems to refer to the third of heaven followed the the dragons tail. (Rev 12:4)
As per Rev 20
The satanic spirit was suppressed for a long time.
1Then I saw an angel coming down from heaven with
the key to the Abyss, holding in his hand a great chain. 2He seized the dragon, that
ancient serpent who is the devil and Satan, and bound him for a thousand years.
The second scrubbing. He was released again to see who who would adhere to the accuser's philosophy, the false doctrines.
7
When the thousand years are complete, Satan will be released from his prison, 8and will
go out to deceive the nations in the four corners of the earth—Gog and Magog—to assemble them for battle. Their number is like the sand of the seashore.
Fire from God. There is you eternal fire.
9And they marched across the broad expanse of the earth and surrounded the camp of the saints and the beloved city. But
fire came down from heaven and consumed them.
10And the devil who had deceived them was
thrown into the lake of fire and sulfur, into which the beast and the false prophet had already been thrown. There
they will be tormented day and night forever and ever.
Forever is literally aeon of aeons. In other words it is up to God as it always was. Consider Berean Literal Bible
10 And the devil, the one deceiving them, was cast into the lake of fire and of sulfur, where the beast and the false prophet also are; and
they will be tormented day and night to the ages of the ages.
When is the end of the epoch.
14
Then Death and Hades were thrown into the lake of fire. This is
the second death—the lake of fire. 15And
if anyone was found whose name was not written in the Book of Life, he was thrown into the lake of fire.
My translation is death and the grave will be annihilated. The presence of God will
eternally be in the lives of the faithful.
The hellmonger's interpretation is the
ghost in hell and
hell will be thrown in
the lake of hell. Kind of loopy snake eating the snakes tail. Another pagan concept.
