And as John the Revelator says..."This calls for wisdom. Let the person who has insight calculate the number of the beast, for it is the number [symbol] of a man. That number is 666 [chi xi stigma]."
The fact that he emphasizes "number/symbol of a man" is confusing.
One might draw from that that John means the single leader (a man) of Islam. Or he might mean "human" as in not a deity but the human followers of such a deity.
I doubt the latter of those suggestions because the Apostle Paul has already told us that we are war with the Spiritual Realm...not the physical/human realm.
Bottom line...I think the AntiChrist is the ultimate leader of Islam...the Caliph.
Obama thinks he is the Caliph...but this chapter isn't over yet.
Obama is the leading figure at present...but time will tell.
Be wise...and clever.
