If you can arrange for him to be "struck to death" and not fully recover for the world to marvel at him, that would suffice.
NOTE TO OMNIVORE: it's a Bible based joke/irony, not a solicitation for any ilegal activity.
Proof that he isn't the antichrist.
Well, starting point I would go for this one is to the book of Daniel and with the prophecy that has to do with the antichrist and where he comes from.
It's the prophecy that Jesus referred to in Daniel and also the one that talks about the Messiah of Israel being "cut-off" and then the "prince that shall come" -- which is the Antichrist.
It's in Daniel Chapter 9 ...
25 Know therefore and understand, that from the going forth of the commandment to restore and to build Jerusalem unto the Messiah the Prince shall be seven weeks, and threescore and two weeks: the street shall be built again, and the wall, even in troublous times. 26 And after threescore and two weeks shall Messiah be cut off, but not for himself: and the people of the prince that shall come shall destroy the city and the sanctuary; and the end thereof shall be with a flood, and unto the end of the war desolations are determined. 27 And he shall confirm the covenant with many for one week: and in the midst of the week he shall cause the sacrifice and the oblation to cease , and for the overspreading of abominations he shall make it desolate, even until the consummation, and that determined shall be poured upon the desolate .
Now, with some Bible prophecy teachers, they are saying that this refers to the Roman Empire and that the prince to come will be from the Roman Empire, which will be the revived Roman Empire of the last days and thus, this prince to come will be from that area, which is Europe (or Eastern Europe, too).
And others say that this prince to come refers to a Syrian component and that this Antichrist will be a Syrian, because the troops were composed of locals in that area and not from the general Roman Empire, so they are saying that this refers to him being a "prince to come" from those whom he commanded.
In all cases, there's no Biblical support for the Antichrist being outside of the Roman Empire (or as the Bible indicates the "revival" of the world empire, the revived Roman Empire, which will rule the world at the time) and thus, not being a part of it.
That's one key and main starting point for identifying the Antichrist. And we can go on from there... but in Obama's case, he can't get beyond just this "starting point" in being the "Antichrist".... LOL...
I personally think Satan has higher standards of competence, but that’s just me.
