Also it causes all, both small and great, both rich and poor, both free and slave, to be marked on the right hand or the forehead, so that no one can buy or sell unless he has the mark, that is, the name of the beast or the number of its name. This calls for wisdom: let the one who has understanding calculate the number of the beast, for it is the number of a man, and his number is 666.
In Revelations 13:18 it somewhat clearly states that the mark of the beast is also the mark of man. And that mark is "the number of its name" which is 666. And that this "mark" is also how we are to, at some point, to use this "mark" as a form of money exchange and business. Which makes me think of credit cards but I digress.
Though I understand that people believe in the devil and that this sorta thing will really happen but I can't help but see this to be a little bit of an irrational fear. Like little children afraid of thunder. They tremble in the sight of the three digits even if they have to do math to find them. They shout "ah ha!" when a gay group has 666 in their address and tell their children "You see. This shows they are not for God. They are for the devil." I wonder do you really think that Satan would be so obvious about his motives? I mean if 666 is hidden into every thing he does well then divide, subtract, and add some digits so we can know! Come on what are you waiting on man this is serious guys!
There are to my knowledge about two bible verses that say the number out right. And there are well over 20 talking about "the beast". "The beast" is believed to be the devil or Satan. Whom is believed to be evil though he only killed about 10 people in the bible and God killed billions. Just a thought but maybe we have our "bad guy" meter is a little off guys.
Anyway I really don't understand the whole fear of those numbers. Even when I believed I thought it was kinda dumb. Maybe that's just me though.
