Do not believe any preacher or any religion that would say that the return of the Lord Jesus Christ already marks the day of judgment and the destruction of the earth. There is no truth to that. Yes, the Lord Jesus Christ will return, but not to judge mankind and destroy the earth right away, as there is another appointed time to carry out those things.
When the Lord Jesus Christ returns, He will resurrect, not all the dead but only those who died in Him. This is called the first resurrection. And then, those whom He resurrected and His faithful servants who are still alive during that time will be caught up in the clouds to meet Him in the air. As it is written in 1 Thessalonians 4:16-17 (KJV),
16 For the Lord himself shall descend from heaven with a shout, with the voice of the archangel, and with the trump of God: and the dead in Christ shall rise first:
17 Then we which are alive and remain shall be caught up together with them in the clouds, to meet the Lord in the air: and so shall we ever be with the Lord.
Those who will be included in the first resurrection are considered blessed because the second death has no power over them anymore. They shall be made priests, and together with Christ, they shall reign on earth for one thousand years.
REVELATION 20:5-6 (KJV)
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.
In other words, there are two resurrections of the dead that are going to happen. The first resurrection is exclusive for those who have died in Christ, and this will happen upon the return of the Lord Jesus Christ; while the second resurrection is inclusive of all the dead that are not included in the first resurrection, and it is going to happen after the one thousand-year period. So, there is a gap of one thousand years between the first and the second resurrection of the dead.
When all the dead have risen, that will be the time when the Lord Jesus Christ shall judge both the living and the dead. The Bible referred to Christ as the judge of both the living and the dead.
1 PETER 4:5 (KJV)
Who shall give account to him that is ready to judge the quick and the dead.
Another verse that proves that the Lord Jesus Christ shall judge both the living and the dead is 2 Timothy 4:1 (KJV), which says,
I charge thee therefore before God, and the Lord Jesus Christ, who shall judge the quick and the dead at his appearing and his kingdom;
There will come a time when the Lord Jesus Christ shall appear and the glory of His kingdom shall be revealed. But it will not be until after the one thousand years, when He shall be passing judgment on both the living and the dead who have risen during the second resurrection.
Actually, John, to whom these revelations were given, had a glimpse of judgment day; he even saw how the devil was cast into the lake of fire and brimstone.
REVELATION 20:10 (KJV)
And the devil that deceived them was cast into the lake of fire and brimstone, where the beast and the false prophet are, and shall be tormented day and night for ever and ever.
After which, John also saw a great white throne, and before the throne of God stood all the dead who have been resurrected to face judgment.
REVELATION 20:11-12 (KJV)
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.
So, it is clear now that the return of the Lord Jesus Christ does not mark the day of judgment nor the destruction of the earth — as these things are going to happen after His reign on earth for a thousand years. It has to be understood that the return of the Lord Jesus Christ only marks the commencement of His millennial reign on earth.
With the Lord Jesus Christ reigning over all those who are on earth, we can just imagine the kind of justice, righteousness, and holiness that will prevail everywhere. We can also expect that with Christ reigning, more and more people will be converted, which means that more and more people will be given the chance to salvation.
