Dan 11:40 "At the time of the end the king of the South shall attack him; and the king of the North shall come against him like a whirlwind, with chariots, horsemen, and with many ships; and he shall enter the countries, overwhelm them, and pass through."
Israel and Egypt Attacking Iran
WW3 will start when the Southern Alliance of Israel and Egypt attack Persia (Iran). No record in Eze 38-39.
Head on Collision with Israel
Eze 38:3, 5 "and say, 'Thus says the Lord GOD: "Behold, I [am] against you, O Gog, the prince of Rosh, Meshech, and Tubal.... Persia, Ethiopia, and Libya are with them, all of them with shield and helmet;"
In WW3 the Northern Alliance will be headed by Persia (Iran), whereas in Eze 38, the collision against Israel will be headed by Russia and Persia is just a member,
Peaceful and Secured Israel
Eze 38:8, 11 "After many days you will be visited. In the latter years you will come into the land of those brought back from the sword and gathered from many people on the mountains of Israel, which had long been desolate; they were brought out of the nations, and now all of them dwell safely.... You will say, 'I will go up against a land of unwalled villages; I will go to a peaceful people, who dwell safely, all of them dwelling without walls, and having neither bars nor gates'
Since the formation of the nation of Israel in 1948, it is constantly under revolts and rebellions with many civilian Jews being harmed or killed - the most dangerous place to stay. The authority is still building a 500km and 8 metre high wall surrounding the West Bank to protect the Israelites.
In Eze 38, Israel then was living in great peace and security with unwalled houses and cities. This can only be possible after WW3, when the Antichrist will sign the 7 year peace treaty to call all Jews to migrate back to Israel to rebuild the temple of God (and also Jerusalem and other cities annihilated during WW3). Since WW3 is the last war before Rapture, then Eze 38 will be after Rapture when God will once free again deal with the Israelites to get them saved.
The West is missing
In WW3, the West (US, EU and UK) and the 5th US Fleet stationed in the Arabian Sea will support Israel and attack Iran, but in Eze 38 the invincible West is missing for they were all annihilated in WW3.
God fighting alongside Israel
Eze 38:18, 21 "And it will come to pass at the same time, when Gog comes against the land of Israel," says the Lord GOD, "that My fury will show in My face... I will call for a sword against Gog throughout all My mountains," says the Lord GOD. "Every man's sword will be against his brother."
In WW3, all those who in Israel were killed but in Eze 38, God protected them
God used WW3 as His vengeance against the abominations committed by Israel causing Jerusalem to be trampled underfoot by its enemies until Rapture. But in Eze 38, God fight alongside Israel and confuses the enemy camp and defeated the enemies surrounding Jerusalem.
Eze 38-39 is not WW3 which is before Rapture, and similarly the temple of God in Eze 40-48 is not the Antichrist's temple of God.
