The Lord's fire will judge all mens works, saved and unsaved alike, "Your Wrong"!
1 Corinthians 3:13KJV
13 Every man's work shall be made manifest: for the day shall declare it, because it shall be revealed by fire; and the fire shall try every man's work of what sort it is.
Rev 20:4
And I saw thrones, and they sat upon them, and judgment was given unto them: and I saw the souls of them that were beheaded for the witness of Jesus, and for the word of God, and which had not worshipped the beast, neither his image, neither had received his mark upon their foreheads, or in their hands; and they lived and reigned with Christ a thousand years.
Before the thousand years even begins, there are thrones and judgment is given to those sitting on the thrones. Then we are introduced to a group of dead Christian martyrs who come back to life. Even the Amill scholar Barnes believes not only is there a judgment here but also states it is these dead martyrs that are being judged and there is only one judgment for them, eternal life!
John sees two groups of people/souls:
1. people sitting on thrones and judgment given to them
2. souls of the tribulation martyrs who instead of remaining dead are said to live with Christ
Claiming 1 and 2 are the same group doesn't make any sense. Those judging are not the second group mentioned. It can only be that second group of martyrs that were being judged and the judgment has to be a resurrection to life which we know is the reward for the dead in Christ.
We see the same event in Daniel:
Dan 7:9 I beheld till the thrones were cast down, and the Ancient of days did sit, whose garment was white as snow, and the hair of his head like the pure wool: his throne was like the fiery flame, and his wheels as burning fire.
Here are multiple thrones and God the Father himself sitting there.
Dan 7:10 A fiery stream issued and came forth from before him: thousand thousands ministered unto him, and ten thousand times ten thousand stood before him:
the judgment was set, and the books were opened.
And here again judgment is mentioned and a large group standing before him. This must be the dead in Christ being judged to life because it cannot apply to the unsaved because the beast hasn't yet been slain:
Dan 7:11 I beheld then because of the voice of the great words which the horn spake: I beheld even till the beast was slain, and his body destroyed, and given to the burning flame.
This beast of course is also seen in Rev 19 being destroyed at the return of Christ. What we then have been given is a judgment of a group before the beast is destroyed so that group must be the saved being judged to eternal life as we also see in Rev 20.
Dan 7:12 As concerning the rest of the beasts, they had their dominion taken away: yet their lives were prolonged for a season and time.
And just like it is for the thousand years, some "beasts" (the wicked/unsaved/and satan himself) have their lives prolonged. Indeed during the thousand years satan and many unsaved gentiles of the world's nations will live through the thousand years.
Rev 20:4
And I saw thrones, and they sat upon them, and judgment was given unto them: and I saw the souls of them that were beheaded for the witness of Jesus, and for the word of God, and which had not worshipped the beast, neither his image, neither had received his mark upon their foreheads, or in their hands; and they lived and reigned with Christ a thousand years.
Before the thousand years even begins, there are thrones and judgment is given to those sitting on the thrones. Then we are introduced to a group of dead Christian martyrs who come back to life. This is a judgment and resurrection of only the saved. The unsaved are judged at a later time and at a later resurrection: "the rest of the dead lived not again until the thousand years were finished" so clearly AFTER the Millennium is when these are resurrected and judged.
Another example of the righteous being judged separately from the wicked:
Mat 25:34 Then shall the King say unto them on his right hand, Come, ye blessed of my Father, inherit the kingdom prepared for you from the foundation of the world:
Mat 25:35 For I was an hungred, and ye gave me meat: I was thirsty, and ye gave me drink: I was a stranger, and ye took me in:
Mat 25:36 Naked, and ye clothed me: I was sick, and ye visited me: I was in prison, and ye came unto me.
Mat 25:37 Then shall the righteous answer him, saying, Lord, when saw we thee an hungred, and fed thee? or thirsty, and gave thee drink?
Mat 25:38 When saw we thee a stranger, and took thee in? or naked, and clothed thee?
Mat 25:39 Or when saw we thee sick, or in prison, and came unto thee?
Mat 25:40 And the King shall answer and say unto them, Verily I say unto you, Inasmuch as ye have done it unto one of the least of these my brethren, ye have done it unto me.
Here we again have judgment of the righteous first! No wicked are being judged with the righteous.
Mat 25:41 Then shall he say also unto them on the left hand, Depart from me, ye cursed, into everlasting fire, prepared for the devil and his angels:
Mat 25:42 For I was an hungred, and ye gave me no meat: I was thirsty, and ye gave me no drink:
Mat 25:43 I was a stranger, and ye took me not in: naked, and ye clothed me not: sick, and in prison, and ye visited me not.
Mat 25:44 Then shall they also answer him, saying, Lord, when saw we thee an hungred, or athirst, or a stranger, or naked, or sick, or in prison, and did not minister unto thee?
Mat 25:45 Then shall he answer them, saying, Verily I say unto you, Inasmuch as ye did it not to one of the least of these, ye did it not to me.
Mat 25:46 And these shall go away into everlasting punishment: but the righteous into life eternal.
Christ does not address time in this but according to Rev 20, there is a period of time inbetween the judgment of the dead in Christ vs. the rest of the dead so we know there is time inbetween these two judgments. Even in human courts there is no such concept of judging someone a reward while judging someone to death. That happens at different times. The two don't belong in one court judgment.
1Pe 4:17 For the time is come that judgment must begin at the house of God: and if it first begin at us, what shall the end be of them that obey not the gospel of God?
As you can see, the righteous are judged FIRST. Judgment starts with "us" as Peter confirms.
