Fast Forward to Armageddon

How and When will this Land Battle Finally End?

Not immediately but this prophecy is ‘for the very end’.

Whose Land is it?

The answer is simple:
It has always been God’s Land & not anyone else’s as the verse below clearly explains this “Fact” when God calls it “My Land” and those who took it prior without His permission ‘made it their own possession’ as it is written:

“This is what the Lord GOD says: Certainly in My burning zeal I speak against the rest of the nations and all of Edom, who took My land as their own possession with wholehearted rejoicing and utter contempt so that its pastureland became plunder.” (Ezekiel 36:5)

P/S:

How will this “last land battle” for the ‘promised land’ end?

“And I saw coming out of the mouth of the dragon and out of the mouth of the beast and out of the mouth of the false prophet, three unclean spirits like frogs;

for they are spirits of demons, performing signs, which go out to the kings of the whole world, to gather them together for the war of the great day of God, the Almighty.

(“Behold, I am coming like a thief. Blessed is the one who stays awake and keeps his clothes, so that he will not walk about naked and men will not see his shame.”)

And they gathered them together to the place which in Hebrew is called Har-Magedon.” (Revelation 16:13 – 16)

So in the ‘end’, ‘they’ will ‘fight God’ and the scene is described as follows in the Book of Revelation:

“And I saw heaven opened, and behold, a white horse, and He who sat on it is called Faithful and True, and in righteousness He judges and wages war.

His eyes are a flame of fire, and on His head are many diadems; and He has a name written on Him which no one knows except Himself.

He is clothed with a robe dipped in blood, and His name is called The Word of God.

And the armies which are in heaven, clothed in fine linen, white and clean, were following Him on white horses.

From His mouth comes a sharp sword, so that with it He may strike down the nations, and He will rule them with a rod of iron; and He treads the wine press of the fierce wrath of God, the Almighty.

And on His robe and on His thigh He has a name written, “KING OF KINGS, AND LORD OF LORDS.”

Then I saw an angel standing in the sun, and he cried out with a loud voice, saying to all the birds which fly in midheaven, “Come, assemble for the great supper of God,

so that you may eat the flesh of kings and the flesh of commanders and the flesh of mighty men and the flesh of horses and of those who sit on them and the flesh of all men, both free men and slaves, and small and great.”

And I saw the beast and the kings of the earth and their armies assembled to make war against Him who sat on the horse and against His army.
And the beast was seized, and with him the false prophet who performed the signs in his presence, by which he deceived those who had received the mark of the beast and those who worshiped his image; these two were thrown alive into the lake of fire which burns with brimstone.

And the rest were killed with the sword which came from the mouth of Him who sat on the horse, and all the birds were filled with their flesh.” (Revelation 19:11 – 21)
