I've been thinking about this for some time. Will this directly affect everyone alive or just indirectly?
Not being allowed to buy and sell unless you have the mark, how can this apllied to every single nation and every single person on Earth? Will there be pockets of resistance or pockets of self-sustenance?
I'll give you an example of what I mean:
World War 2 was called World War 2 because it affected the entire World and was a war that spanned the globe. Not every nation was involved however, in fact most were not, but every nation was affected by it in some way or another, either at the time or shortly afterwards. Some nations were hardly affected at all, but nevertheless were acutely aware of what was going on.
Will the reign of the anti-christ be the same? I mean, if it literally does involve submission on the part of every single person on the planet, then who will be there to resist this submission and tell others to resist too? There has to be a resistance movement or free areas that try to fight back.
If the entire World is under submission then how can there be a Mystery Babylon? How can sailors watch her burn from afar (Rev 18:17) and mourn for her? Would the beast allow these sailors to be freely sailing in ships?
