That's also a generalization of events, because we know that the earth doesn't pass away in conjunction with the Lord coming to gather his church.
The receiving of the new bodies (everyone) one will occur in the twinkling of the eye. It will not be done in shifts, some on the last day then another group in a literal thousand years later. The thousand years in Revelation 20 clearly represent a unknown of whatever is in view whether its time sensitive or not. He will come in the thief in the night (once) just as he came in the flesh for a demonstration of the true work (once.)
There will be no kingdom of God on this corrupted creation on earth not even for the twinkling of the eye. Corruption does not inherit the incorruptible
The revelation that John received is from the standpoint of the last day(day of the Lord) looking back. The events that are signified are revealed by a sign .The word signified reveals a parable is at hand It sets the standard for understanding the book.
Rev 1:1 The Revelation of Jesus Christ, which God gave unto him, to shew unto his servants things which must shortly come to pass; and he sent and signified it by his angel unto his servant John:
Signs of observation(not signs to seek after) are needed when comparing the spiritual things not seen of God found in parables to be compared to the same spiritual meaning hid from the lost. Without parables Christ spoke not.
In verse 10 the “Lord’s day” signifies the last day the trumpet the final it’s the end of time
Rev 1:10 I was in the Spirit on the Lord's day, and heard behind me a great voice, as of a trumpet,
Its the last day ... hearing the sound of the seventh trumpet all in the twinkling of the eye
Saying, I am Alpha and Omega, the first and the last: and, What thou seest, write in a book, and send it unto the seven churches which are in Asia; unto Ephesus, and unto Smyrna, and unto Pergamos, and unto Thyatira, and unto Sardis, and unto Philadelphia, and unto Laodicea. And I turned to see the voice that spake with me. And being turned, I saw seven golden candlesticks;Rev 1:11
The voice of God is signified by a trumpret in the above parable it is represented by that see the tenmporal (seven golden candlesticks) to represent the bossum of Abraham the invisible presence of God.
The chain in Revelation 20 signfies the binding authority of the gospel . The bottomless pit the never ending justice . the word dragon or serpent signidied the the lying spirt who has no form the god of this world.
What do you think the word thousand years signifies in that parable?
Since the revelation is signified using signs as shadows we should start to look to the parables.Ignoring them can lead a person to another conclusion of there own design
