You are allowing men's false doctrine of Amillennialism to confuse you.
Premillennialism is "men's false doctrine" because it contradicts a great deal of clear, straightforward scriptures. The way you butcher straightforward text like 2 Peter 3:10-12 is evidence of that.
The Revelation 22:14-15 Scripture is Revelation 20 "thousand years" timing.
Nope. That's complete nonsense. All of Revelation 21 and 22 relates to the eternal new heavens and new earth and the eternal lake of fire. It has nothing to do with the thousand years. It's funny to me how you can decide that Revelation 22:14-15 does not occur chronologically after what is described in Revelation 20:1-6, but you refuse to even consider that what is described in Revelation 20 does not occur chronologically after what is described in Revelation 19. At least you recognize that some of the book is not in chronological order, but that's a small consolation for not recognizing the chronological order of Revelation 20-22 properly.
Just as with the Old Testament prophets, not everything written happens in sequence. And didn't you claim the wicked are in the "lake of fire" per that Rev.22 Scripture? For you to believe that it means you MISSED what Jesus showed about the place of separation that begins at His return where the wicked are cast to, i.e., the "outer darkness". You wrongly claim that is the "lake of fire", which it is not.
Both "outer darkness" and the "lake of fire" are symbolic ways of referring to the final destination of the wicked. Being cast into outer darkness and being cast into the lake of fire, which can also be referred to as a furnace of fire or "everlasting fire prepared for the devil and his angels", as Jesus did, result in weeping and gnashing of teeth. They are referring to the same thing.
Matthew 8:12 But the sons of the kingdom will be
cast out into outer darkness. There will be weeping and gnashing of teeth.”
Matthew 13:41 The Son of Man will send out His angels, and they will gather out of His kingdom all things that offend, and those who practice lawlessness, 42
and will cast them into the furnace of fire. There will be wailing and gnashing of teeth.
Matthew 13:49 So it will be at the end of the age. The angels will come forth, separate the wicked from among the just, 50 and
cast them into the furnace of fire. There will be wailing and gnashing of teeth.”
Matthew 22:13 Then the king said to the servants, ‘Bind him hand and foot,
take him away, and cast him into outer darkness; there will be weeping and gnashing of teeth.’
Matthew 24:50 the master of that servant will come on a day when he is not looking for
him and at an hour that he is not aware of, 51 and will cut him in two
and appoint him his portion with the hypocrites. There shall be weeping and gnashing of teeth.
Matthew 25:30 And cast the unprofitable servant
into the outer darkness. There will be weeping and gnashing of teeth.’
Matthew 25:41 “Then He will also say to those on the left hand, ‘
Depart from Me, you cursed, into the everlasting fire prepared for the devil and his angels:
Revelation 20:15 And
anyone not found written in the Book of Life was cast into the lake of fire.
I believe it's ludicrous to deny that all of these verses are speaking of the same event. Unbelievers whose names are not written in the book of life are not going to be cast to where there will be weeping and gnashing of teeth on more than one occasion.
