I have a link here that is in some ways what i have in mind when I think about the whole topic of the "End Times"
http://www.compellingtruth.org/Muslim-antichrist.html
Now the link might suggest that the Anti-Christ and the 12th imam are the same guy, but when i read the Scriptures I just dont see that being necessarily true.
I have always had a feeling that the Anti-Christ will be someone who can unite the Jew, Islam, and Christians under one banner.
I have always felt that the Bible's False Prophet is connected to Islam and could be seen as the highly expected 12th Imam.
Also, when so many teachers on the End times talk about a limited "7 year tribulation" I don't believe that for a moment....
I believe that all the teachers that have their whole end times time-line all centered around a limited '7 year Tribulation" are guilty of doing Bable math and thinking that they can add things up like that , when in truth we simply cant expect the bible to talk and teach like that....
