The mark of the beast is constant. It’s already determined. It is our understanding of what form that mark takes that is evolving with technology. When you find that some mark, be it a chip or barcode or something else, becomes necessary in order to conduct commerce, then that’s a pretty good clue that it is The Mark.
Although I didn't say it in the words you used, that was the point I've been making on every post on this thread.
The other point I've been making is that all these calls that this thing, or that thing, is "The Mark of the Beast" from people who claim to know are bogus.
Similar to calls of 'He's the anti-Christ'.
Isn’t some form of mark, chip, barcode or something else, already required to conduct commerce? We’ve been using currency, signatures, chops, validation numbers, pieces of gold, etc, since commerce began.
