Your claim is in error, the final judgement takes place in Revelation 20:11-15
Revelation 20:11-15KJV
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.
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.
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.
14 And death and hell were cast into the lake of fire. This is the second death.
15 And whosoever was not found written in the book of life was cast into the lake of fire.
Your claim is in error. What you're talking about is the carrying out of the decreed sentence, because that judgment spoken of in Revelation 20:11-15 has already come.
You need to believe Jesus when He speaks:
John 12:31-32
"Now is the judgement of this world. Now shall the prince of this world be cast out. And I, if I am lifted up from the earth, I will draw all to Myself."
Revelation 12:9-11
"And the great dragon was cast out, the old serpent called Devil, and Satan, who deceives the whole world. He was cast out into the earth, and his angels were cast out with him. And I heard a great voice saying in Heaven,
Now has come the salvation and power and the kingdom of our God, and the authority of His Christ. For the accuser of our brothers is cast down, who accused them before our God day and night. And they overcame him because of the blood of the Lamb, and because of the word of their testimony. And they did not love their soul to the death."
John 3:17
"For God did not send His Son into the world to condemn the world,
but so that the world might be saved through Him. He who believes on Him is not condemned,
but he who does not believe is condemned already, because he has not believed in the name of the only-begotten Son of God."
120 years before the flood, God judged the world, and the world was found guilty:
Genesis 6:5-7
"And the LORD saw that the wickedness of man was great in the earth, and every imagination of the thoughts of his heart was only evil continually. And the LORD repented that He had made man on the earth, and He was angry to His heart. And the LORD said, I will destroy man whom I have created, from the face of the earth, both man, and beast, and the creeping thing, and the fowls of the air. For I repent that I have made them."
Genesis 6:13-14a
"And God said to Noah, The end of all flesh has come before Me, for the earth is filled with violence through them. And, behold, I will destroy them with the earth. Make an ark of Cyprus timbers. You shall make rooms in the ark..."
Genesis 6:3
"And the LORD said, My spirit shall not always strive with man, in his erring; he is flesh. Yet his days shall be a hundred and twenty years."
The world, in the days of Noah,
was not judged on the day the floods came. The flood was just the carrying out of the decreed sentence
which had already been passed when the world was judged 120 years earlier. God had
already judged the world, and the world had
already been found guilty. The sentence had been decreed, but not carried out yet. There was still a chance to get into the ark, and many were no doubt called into the ark, but few (8 souls) were chosen.
The ark is a picture of Christ:
John 3:17
"For God did not send His Son into the world to condemn the world,
but so that the world might be saved through Him. He who believes on Him is not condemned,
but he who does not believe is condemned already, because he has not believed in the name of the only-begotten Son of God."
Hebrews 11:7
"By faith Noah, having been warned by God of things not yet seen, moved with fear, prepared an ark to the saving of his house,
by which he condemned the world and became heir of the righteousness which is by faith."
2 Peter 3:9
"The Lord is not slow concerning His promise, as some count slowness, but is long-suffering toward us, not willing that any of us should perish, but that all of us should come to repentance."
When the world was judged, the judgement fell on Christ, and
just as the floods came upon the ark, but the ark was lifted up (and out of the destruction) while those in the ark were saved (but only those in the ark), so Christ bore the judgement of the world, was lifted up from the earth, and He is our ark, the ark of those who are IN HIM through faith in Him.
So if we
believe the words
of Jesus and the Revelation Jesus has given us, then we will understand that God’s judgement
has already come, but the decreed sentence is yet to be carried out. What will occur at the time of the return of Christ is not "the" judgement (because the judgement of this world came when Christ died on the cross), but it will be
a judgement, because
whenever the wrath of God is poured out upon people or nations, it’s a judgement.
What will occur at the time all souls appear before the Great White Throne is the carrying out of the decreed sentence; and Jesus is our Ark.
Hebrews 1:1-2
"God, who at many times and in many ways spoke in time past to the fathers by the prophets, has in these last days spoken to us by His Son, whom He has appointed heir of all things, by whom also He made the worlds."
"The last days" in Noah's day was the 120 years before the flood came.
