In 2 Peter 2:4 Peter claimed the sinful angels had not yet been judged. How could they be sentenced to everlasting fire if they have not yet been judged?
We won't judge these angels until the Last Day, the Great Day.
Chained in Hell;
reserved for judgement.
This is the final judgement:
Rev. 20:11 Then I saw a great white throne and Him who sat upon it, from whose presence earth and heaven fled away, and no place was found for them. 12 And I saw the dead, the great and the small, standing before the throne, and books were opened; and another book was opened, which is the book of life; and the dead were judged from the things which were written in the books, according to their deeds. 13 And the sea gave up the dead which were in it,
and death and Hades gave up the dead which were in them; and they were judged, every one of them according to their deeds. 14 Then death and Hades were thrown into the lake of fire. This is the second death, the lake of fire.
Their final judgement is the Lake of Fire. Until THAT day they are chained in Hell and reserved for this judgement.
There is no redemption for them.
Finish your chapter...2 Peter 2:9 then the Lord knows how to rescue the godly from temptation, and t
o keep the unrighteous under punishment for the day of judgment, 10 and especially those who indulge the flesh in its corrupt desires and despise authority.
