To understand this, we must first determine when judgment occurs. The church is being judged now...
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?
Notice Rev 20...
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.
Rev 20:5 But the rest of the dead lived not again until the thousand years were finished. This is the first resurrection.
Rev 20:6 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.
There is no mention of judgment on these, they were already judged during their life. Now notice those raised in the Great White Throne Judgment...
Rev 20:11 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.
Rev 20:12 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.
These are judged at this future resurreciton.
Also the third resurrection, the resurrection to damnation as Christ put it in John 5:29 and Daniel referred to it in Dan 12:2...
Rev 20:13 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.
Rev 20:14 And death and hell were cast into the lake of fire. This is the second death.
Rev 20:15 And whosoever was not found written in the book of life was cast into the lake of fire.
The church is judged now...
1Co 11:31 For if we would judge ourselves, we should not be judged.
1Co 11:32 But when we are judged, we are chastened of the Lord, that we should not be condemned with the world.
We need to inspect our own lives now and correct our faults and sins that we are not judged by Christ. If we do not, or do not recognize our faults and sins, Christ will judge and correct us...
Heb 12:5 And ye have forgotten the exhortation which speaketh unto you as unto children, My son, despise not thou the chastening of the Lord, nor faint when thou art rebuked of him:
Heb 12:6 For whom the Lord loveth he chasteneth, and scourgeth every son whom he receiveth.
Heb 12:7 If ye endure chastening, God dealeth with you as with sons; for what son is he whom the father chasteneth not?
Heb 12:8 But if ye be without chastisement, whereof all are partakers, then are ye bastards, and not sons.
Heb 12:9 Furthermore we have had fathers of our flesh which corrected us, and we gave them reverence: shall we not much rather be in subjection unto the Father of spirits, and live?
Heb 12:10 For they verily for a few days chastened us after their own pleasure; but he for our profit, that we might be partakers of his holiness.
Heb 12:11 Now no chastening for the present seemeth to be joyous, but grievous: nevertheless afterward it yieldeth the peaceable fruit of righteousness unto them which are exercised thereby.
Heb 12:12 Wherefore lift up the hands which hang down, and the feeble knees;
Heb 12:13 And make straight paths for your feet, lest that which is lame be turned out of the way; but let it rather be healed.
