How come the Antichrist is not in the book of revelations?
He is the “beast” in Revelation and called the “man of sin” in 2 Thess. 2:3. All the references in Revelation to the beast are the “Antichrist” or “man of sin”, except one passage: Rev 13:11 And I saw another beast coming up out of the earth. And it had two horns like a lamb, but spoke like a dragon. Rev 13:12 And it executes all the authority of the first beast before it. And it causes that the earth and those dwelling in it should worship the first beast, of which was healed its deadly wound. Here it is speaking of the false prophet.
