The Bible NEVER mentions "antichrist" in Revelation. Here are the only mentions:
(Please note that there are MANY antichrists and have been for thousands of years from these verses):
1John 2:18-19 (2x)
18 Children, it is the last hour; and just as you heard that antichrist is coming, even now many antichrists have appeared; from this we know that it is the last hour. 19 They went out from us, but they were not really of us; for if they had been of us, they would have remained with us; but they went out, so that it would be shown that they all are not of us.
1John 2:22
22 Who is the liar but the one who denies that Jesus is the Christ? This is the antichrist, the one who denies the Father and the Son.
1John 4:2-3
2 By this you know the Spirit of God: every spirit that confesses that Jesus Christ has come in the flesh is from God; 3 and every spirit that does not confess Jesus is not from God; this is the spirit of the antichrist, of which you have heard that it is coming, and now it is already in the world.
2John 1:7
7 For many deceivers have gone out into the world, those who do not acknowledge Jesus Christ as coming in the flesh. This is the deceiver and the antichrist.
*One of the most deceptive things I've seen is a recent "Jesus gives the name of the antichrist" youtube video.
It is VERY DECEPTIVE!
Have you seen it?
It makes several deceptive translations from English to Greek to Aramaic to Hebrew and then back to say "baw-rawk bamaw" is "lightning" falling from "the heights" referring to Satan.
It's horsecrap and my fellow Bible believing Christians need to shut THE HELL up about it.
One of the heroes of the Bible in Hebrews 11:31 is "Barak."
There are plenty of reasons a Christian can principly oppose President Obama and his policies, but if Hitler, Stalin and Nero didn't get Jesus off His throne to return, President Obama NEVER will it seems.
