the mark has to be a byproduct of the current system. the way things are going soon there will be a mark or chip in every person that forms part of the new economic system. taking hold of us for a couple of decades now.
I should say one more thing here to make it clear what the Bible says is "really" the "Mark of the Beast" ...
If I were to get that tatoo right now, or get some hi-tech chip put in me, right now, that would somehow have some interaction with my buying and selling and I could "buy" things and "sell" things in conjunction with this mark that I could get right now -- that would not be the Mark of the Beast. I would be just fine, according to what the Bible warns about. I would have no problems there, as far as God was concerned.
The "real problem" with the "Mark of the Beast" is that (1) you have the Beast (the Antichrist) identified and known, and (2) you get the mark, which says that's your agreement to worship the Beast as "God" -- and it's only in that context that the Bible gives the warning about the Mark of the Beast.
Right now there's no Biblical warning for anything that we have, right now, anywhere in the world, that is the "Mark of the Beast" no matter what anyone does.
That's not to say that one of these things, right now, might not be used -- "when" -- the Antichrist does show up and "when" he does demand worship as God, but that's not right now.
Both God and Satan exist outside of the time continuum. that gives them plenty of time so to speak to put in place a trial of the human race. My thinking is that Satan will appear as God and mislead billions, especially the new age crowd. I pray and hope for salvation. May God guide me through this turmoil.
I still say Sharia Law is the “Mark” and falls in line with buying and selling and ingrains the worship of Allah in all transactions.
If the banking system crashes, tadaaaa, in comes the savior system with Arab financial backing.
