However, I think the greatest
deception will take place when the Antichrist
and False Prophet do great signs and lying
wonders and people end up worshipping the beast
and his image and receive the mark of the beast
in the forehead or the right hand which will
damn them eternally to the lake of fire.
2 Thess. 2:8-12, "
And then shall that Wicked be revealed, whom the Lord shall consume with the spirit of his mouth, and shall destroy with the brightness of his coming: Even him, whose coming is after the working of Satan with all power and signs and lying wonders, And with all deceivableness of unrighteousness in them that perish; because they received not the love of the truth, that they might be
saved. And for this cause God shall send them strong delusion, that they should believe a lie: That they all might be
damned who believed not the truth, but had pleasure in unrighteousness."
