All this shows is that during one resurection both types of people are raised. Not two resurrections. I think the verse is very clear here. Note "all" that are in their graves. 2 dispensing of judgement 1) eternal reward and 2) eternal damnation. But both are raised. 1 ressurection here.
1 resurrection 2 dispensing of judgement.
No passage of Scripture could be any clearer than this one.
The hour that is to come simply refers to a period of time, not a specific hour. There is a time coming when...there will be two resurrections. It is Scripture, the teaching of Christ.
It speaks of two resurrections. Two separate times--not one general resurrection. If Jesus meant one general resurrection he would have said that but he didn't. He mentioned and stated two distinct separate resurrections for two distinct separate people--just and unjust.
He repeated the same elsewhere:
And I saw an angel come down from heaven, having the key of the bottomless pit and a great chain in his hand.
2 And he laid hold on the dragon, that old serpent, which is the Devil, and Satan, and bound him
a thousand years,
3 And cast him into the bottomless pit, and shut him up, and set a seal upon him, that he should deceive the nations no more, till
the thousand years should be fulfilled: and after that he must be loosed a little season.
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.
5
But the rest of the dead lived not again until the thousand years were finished. This is the first resurrection.
6 Blessed and holy is he that hath part in the first resurrection: on such the second death hath no power, but they shall be priests of God and of Christ, and shall reign with him
a thousand years.
7 And when
the thousand years are expired, Satan shall be loosed out of his prison, (Revelation 20:1-7)
There is the first resurrection--vs. 6: Blessed and holy is he that hath part in the first resurrection. It takes place first--a thousand years before the second resurrection.
There is the second resurrection:
And I saw a great white throne, and him that sat on it, from whose face the earth and the heaven fled away; and there was found no place for them. And I saw the dead, small and great, stand before God; and the books were opened: and another book was opened, which is the book of life: and the dead were judged out of those things which were written in the books, according to their works. And the sea gave up the dead which were in it; and death and hell delivered up the dead which were in them: and they were judged every man according to their works. And death and hell were cast into the lake of fire. This is the second death. And whosoever was not found written in the book of life was cast into the lake of fire. (Revelation 20:11-15)
Note in verse six that those in the first resurrection, the second death has no power.
Those in the second resurrection, which happens a thousand years later appear here before the Great White Throne Judgment. Many times is the "thousand years" used stressing that this is no allegorical number but an actual period of time in the future of mankind. Two resurrections separated by a thousand years.
BTW, John wrote this book as well as the Gospel of John, both of which speak of these same resurrections.
