In a previous answer you said, “The reason all nations come to Jerusalem is not to fight against the anti-Christ. It’s to fight alongside him against Jesus.” Does this mean that the nations will know very well who Jesus is at this time? They will know He is Lord and that they are choosing to fight Him for planet earth?
Yes, in effect that’s just what it means. But remember, they’ll think the anti-Christ is God and Jesus is the enemy. They’ll be persuaded they can defeat Him because they’ll think they have God on their side. This is the lie Paul spoke about in 2 Thes.2:4. About those days Rev. 13:4 says, “Men worshiped the dragon (Satan) because he had given authority to the beast (anti-Christ), and they also worshiped the beast and asked, “Who is like the beast? Who can make war against him?”
Psalm 2:2-3 also prophesied this. The kings of the earth take their stand and the rulers gather together against the Lord and against his Anointed One. “Let us break their chains,” they say, “and throw off their fetters.”
This shows the extent to which an unsaved person can be deceived.
