it's metaphorical, it means your thoughts and your works, not a literal tattoo on your forehead, then NO ONE would get it because it would be WAY TOO OBVIOUS and supposedly a lot of people will get it
i already did, "your works", not a native english speaker, probably should have said "your actions"
well, I don't know what the mark is or what the name is, so, so far I don't really have an answer to that, my interpretation is, I guess, that the thoughts or actions would be with the same will of the beast, doing the beasts will.
I'm just saying, if it's a chip or a tattoo or anything like that in your hand or your forehead, then everyone will be able to say "look here in the bible" and everyone who has ever even slightly believed in the bible will not take it, and I've at least been led to believe that even people who at least claim to be christian will receive it
I guess shouldn't say "it is so" but I'm very convinced that it is
