That's what everyone is saying...but the scriptures simply do not state that about the mark....all it says is that the Beast will CAUSE all to receive it, but it doesn't state it's in allegiance to him at all. There is a GREAT DECEPTION, which also is not described, involved with the beast and the mark...does everyone think the mark of the beast will be clearly defined for all and sundry so they can choose? If one believes that, it's not in the scriptures at all, so no basis for it.
And, one has to consider, anyone taking the vaccine IS doing it with full knowledge that Satan has given them and them believing the lie from the Father of Lies IS allegiance to Satan. So many warnings and truth out there about Covid and the vax but you've seen how many adamantly deny those truths and even get angry when you present them to them....why the anger? If they don't believe it, they are free to discard it, but they don't....they get very angry and try to suppress the truth. Sound familiar?
It all has to do with deception and not just any deception but a GREAT deception, that ~if it were possible!~even the elect would believe it~and that great deception is world wide....when was the last time you saw a world wide deception like we are seeing now? Apparently, the true elect are informed by the Holy Spirit not to believe the great deception, thus making it impossible for them to fall for it......and those who are not are not being given that discernment, are indeed believing it.
