'Book of Daniel'
Dan 11:32 “Those who do wickedly against the covenant he shall corrupt with flattery; but the people who know their God shall be strong, and carry out great exploits.”
The whole world who had witnessed the incarnation of the Antichrist, will follow him accepting him as God's send.
For the past 2-3 decades, the fallen angels (demons) have caused great sufferings to men with natural disasters and extreme weather (c.f sufferings of Job). These demons have also caused havoc worldwide in revolts, riots, rebellions, confusions, fears, and racial and religious disharmony resulting in many countries especially the West in political and racial disarray, corruption, betrayal and hatred.
However, knowledgeable Christians will reject and expose the Antichrist as the incarnate of Satan.
Rev 13:3 And I saw one of his heads as if it had been mortally wounded, and his deadly wound was healed. And all the world marveled and followed the beast.
Those who do wickedly against the covenant he shall corrupt with flattery
As soon as the Antichrist with his Satanic powers annihilated the invincible fleets of West and overran Israel, he will persecute and kill Christians. For the sake of security, benefits, positions, these faithless Christian leaders, gay bishops, covetous, carnal, worldly and rich televangelists, pastors, church leaders, false prophets and teachers, will apostate and follow him.
These apostates along with the many misled Muslims in the West will rebel against their own authorities by sabotaging whatever is in sight causing their own countries to self-destruct.
Judgment of God
1 Pet 4:17-18 For the time has come for judgment to begin at the house of God; and if it begins with us first, what will be the end of those who do not obey the gospel of God.
To prepare His bride for Rapture, God will use World War 3 to judge the world starting from His house (church and countries). All these apostates and heretics, abominable, unmerciful, lawless, carnal and covetous pastors, prophets, leaders and televangelists will escape the Antichrist's wrath, but they will not be able to escape God's judgment.
God will also judge and kill all extremists, murderers, terrorists and jihadist.
World War 3 will see the destruction of powerplants, factories, transportation, farmlands, warehouses. Without power, fuel and transportation, everything will grind to a halt. Food will be left to rot in farmlands, warehouses and places of storage. Along with the natural calamities of great earthquakes, huge tsunamis, pestilences, plagues, famines, everyone will starve and this will be worse than the starvation during the siege of Jerusalem where parents ate their babies and little children. Plagues from camels, pigs, dogs, cats and rats, (beasts) will be responsible for the death of many.
Removal of Tares
Mat 13:40-42 Therefore as the tares are gathered and burned in the fire, so it will be at the end of this age. The Son of Man will send out His angels, and they will gather out of His kingdom all things that offend and those who practice lawlessness and will cast them into the furnace of fire. There will be wailing and gnashing of teeth.
In the last days, God will send His angels to harvest the tares first. He will use World War 3, the last war before Rapture, to kill all those tares (carnal, faithless, abominable, depraved and heretic Christian leaders) and send them to the fire of Hades before He begins His greatest end-time harvest of souls (wheat).
Phi 3:18-19 For many walk, of whom I have told you often, and now tell you even weeping, that they are the enemies of the cross of Christ: whose end is destruction, whose god is their belly, and whose glory is in their shame—who set their mind on earthly things.
God's Complete Protection
Since all those killed will be cast into Hades, I thank our beloved Father God that faithful Christians will be protected and empowered by Him during World War 3 as promised in Psalm 91.
