The war at the end of the 1000 years involves every country attacking Israel. Ezekiel 38 and 39 are just a few nations.
Many peoples will take part in this Gog Magog war..
1 And the word of the LORD came unto me, saying, 2 Son of man, set thy face against
Gog, the land of Magog, the chief prince of
Meshech and
Tubal, and prophesy against him, 3 And say, Thus saith the Lord GOD; Behold, I am against thee, O Gog, the chief prince of Meshech and Tubal: 4 And I will turn thee back, and put hooks into thy jaws, and I will bring thee forth, and all thine army, horses and horsemen, all of them clothed with all sorts of armour, even a great company with bucklers and shields, all of them handling swords: 5
Persia, Ethiopia, and
Libya with them; all of them with shield and helmet: 6
Gomer, and all his bands; the house of
Togarmah of the north quarters, and all his bands: and
many people with thee.
Note the nations mentioned Persia, Etheopia, and Lybia.. Do you ever wonder where is Egypt or Iraq ( Sinar ) and Syria and Lebanon are ???? One thing we learn about the Millennial kingdom is that it will include Egypt, Sinar and placed like Syria and Lebanon and the Arabian peninsular.. This is why these nations are not mentioned,, Because when this prophecy is fulfilled they will no longer exist..
And of course as you mentioned the state of peace and tranquility The Kingdom will be in when this was starts..
(Ezekiel 38:8-11) "¶ After many days
thou shalt be visited: in the latter years thou shalt come into the land that is brought back from the sword, and is gathered out of many people, against the mountains of Israel, which have been always waste: but it is brought forth out of the nations, and they shall dwell safely all of them. {9} Thou shalt ascend and come like a storm, thou shalt be like a cloud to cover the land, thou, and all thy bands, and many people with thee. {10} Thus saith the Lord GOD; It shall also come to pass, that at the same time shall things come into thy mind, and thou shalt think an evil thought: {11}
And thou shalt say, I will go up to the land of unwalled villages; I will go to them that are at rest, that dwell safely, all of them dwelling without walls, and having neither bars nor gates,"
They will attack an Israel without Walls without security bars over their windows.. With no gates even?? Si there any society on earth at the moment who lives in a society so safe that they need no walls or even gates?? But will such a society exists during the 1000 year reign of the LORD Jesus? Yes indeed there will be.. Also who is going to visit them ( gog / magog ) lets read Revelation 20..
(Revelation 20:7-8) "And when the
thousand years are expired,
Satan shall be loosed out of his prison, {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."
So after the 1000 years have expired Satan will visit them and deceive them and gather them to go and fight against the Kingdom..
So how will the LORD destroy the army of Gog ?
(Ezekiel 38:22-23) "And I will plead against him with pestilence and with blood; and I will rain upon him, and upon his bands, and upon the many people that are with him, an overflowing rain, and
great hailstones, fire, and brimstone. {23} Thus will I magnify myself, and sanctify myself; and I will be known in the eyes of many nations, and they shall know that I am the LORD."
And how will the LORD destroy the army of God in Revelation 20?
(Revelation 20:9) "And they went up on the breadth of the earth, and compassed the camp of the saints about, and the beloved city: and
fire came down from God out of heaven, and devoured them."
Yes a lot of well known prophecy preachers online and elsewhere think Ezekiel 38 war will happen Before the return of Jesus.. But for the above reasons i see it as at the end of the 1000 year kingdom..
