how is that inline with Matthew 5:5 “Happy are the mild-tempered
+ ones, since they will inherit the earth.?
Obviously someone is going to be here
After the 1000 year millennium the New Jerusalem along with the saints will come down from heaven as we see in Revelation 21.
Revelation 21:2
And I John saw the holy city, new Jerusalem, coming down from God out of heaven, prepared as a bride adorned for her husband.
After the thousand years, Christ returns to the earth to execute final judgment on the rejecters of His truth, and to take back that which is rightfully His. It is then that the kingdom will be restored to the saints.
The prophet Zechariah describes the coming of the Lord with all His saints, and how the feet of the Lord touch the earth to create a great plain, something that did not happen at the Second Coming.
Zechariah 14:4-5
4 And his feet shall stand in that day upon the mount of Olives, which is before Jerusalem on the east, and the mount of Olives shall cleave in the midst thereof toward the east and toward the west, and there shall be a very great valley; and half of the mountain shall remove toward the north, and half of it toward the south.
5 And ye shall flee to the valley of the mountains; for the valley of the mountains shall reach unto Azal: yea, ye shall flee, like as ye fled from before the earthquake in the days of Uzziah king of Judah: and the Lord my God shall come, and all the saints with thee.
Notice closely the text which says, 'and the Lord my God shall come, and all the saints with thee.' The ancient prophecies made to literal Israel could have had their fulfilment in Israel of old if they had been obedient to God. The old covenant promises were transferred to spiritual Israel when they rejected the Messiah. The essence of the prophecy in Zechariah thus still applies and reaches its final fulfilment in the return of Christ after the millennium.
So after the 1000 year millennium, the New Jerusalem then descends from heaven...
And I, John, saw the holy city, New Jerusalem, coming down from God out of heaven, prepared as a bride adorned for her husband.
Revelation 21:2
From the safety of the city, the saints will then witness the final events which will end the great controversy between Christ and Satan. Satan will have had a thousand years to reflect upon the consequences of his actions and the sentence that awaits him.
Revelation 20:7
7 And when the thousand years are expired, Satan shall be loosed out of his prison,
Satan had been bound when the wicked were slain at the first coming of Christ. The wicked that died would not come to life until a thousand years had expired.
But the rest of the dead lived not again until the thousand years were finished...
Revelation 20:5
The resurrection of the wicked of all ages looses the chains of circumstances which had bound Satan, and he spurns the resurrected millions on to take the Holy City in one final effort to retain power.
Revelation 20:8
And shall go out to deceive the nations which are in the four quarters of the earth, Gog, and Magog, to gather them together to battle: the number of whom is as the sand of the sea.
In Ezekiel 38:2, Gog, the king of Magog is described as an enemy of God's people.
Ezekiel 38:2
Son of man, set thy face against Gog, the land of Magog, the chief prince of Meshech and Tubal, and prophesy against him
He is described as the leader of the host that would attack restored Israel. but he would meet his end. This would happen "after many days" (Ezekial 38:8) and we see the events..
Ezekiel 38:18-19
18 And it shall come to pass at the same time when Gog shall come against the land of Israel, saith the Lord God, that my fury shall come up in my face.
19 in my jealousy and in the fire of my wrath have I spoken, Surely in that day there shall be a great shaking in the land of Israel;
God destroys Gog and Israel does not battle at all. No historic figure has as yet been identified with Gog, and he stands as a symbol of the leader of rebellion, Satan himself.
God permits this final act of rebellion by Satan and his hosts together with the resurrected wicked to dispel any lingering doubt as to the antipathy of those arraigned against God and His people. Good and evil stand opposite each other. The saints within the city, the wicked without and Satan and the wicked will be destroyed by fire.
...and fire came down from God out of heaven and devoured them. The devil, that deceived them, was cast into the lake of fire and brimstone...
Revelation 20:9,
10
With this final destruction of Satan, the great controversy ends. Satan and his host (Gog and Magog) are destroyed by fire.
