The False Prophet

The false prophet is the only human of the evil trio. He is pictured in Revelation 13:11 as the beast that comes up out of the earth. We know this beast is the false prophet because when we compare what he does with what the false prophet does, itís identical.
And he deceives those who dwell on the earth because of the signs which it was given him to perform in the presence of the beast. Revelation 13:14a

And the beast was seized, and with him the false prophet who performed the signs in his presence, by which he deceived those who had received the mark of the beast and those who worshiped his image. Revelation 19:20a
We know that he is a human because Revelation 13:18 says that his number is that of a man. Also, the imagery of him coming up out of the earth in contrast to coming up out of the sea or abyss indicates a natural origin in the sense that Adam was from the earth.

Revelation 13:11 also states that the false prophet speaks like a dragon. This would indicate that he is possessed by Satan, the dragon. This is in keeping with how Paul describes the man of sin.
The one whose coming is in accord with the activity of Satan, with all power and signs and false wonders. 2 Thessalonians 2:9
Notice that the false prophet is always in the presence of the beast when he is described as performing the signs and wonders that deceive the world. This would explain the reason for Satan giving his power, throne, and great authority to the other evil angel, the beast. He does so to enter the false prophet and coordinate with the evil angel beast to bring about the supernatural signs and wonders that will deceive the world into believing that he is God. At some point, he goes to Jerusalem and actually declares himself to be God. His mark, and the image, will then be used to purge the world of those who refuse to worship him.

The false prophet is also known as the man of sin, the son of perdition, or the Antichrist. All of these terms are synonymous and refer to the only human of the evil trio who is described in Revelation 13 as the beast who comes up from the earth and is referred to as the false prophet.
