Revelation Chapter 13. Just what is The Mark of the Beast?

Today we finish Revelation Ch 13:5-18, Just what is this mark of the beast? It's not a vaccine, a barcode, a tattoo, it's not anything you'll be tricked into doing... The Mark of the Beast is a mark that the world will be more than excited to take, it's a mark that glorifies this man. a mark that the earth dwellers will take to say they love the beast, they believe he is god, or they may take the mark so they can buy and sell, to fit in, to continue living in their life style, to not become a misfit, they will cry and say: Who is like the beast? who is able to make war with him?
Let Him who has understanding calculate the number of the beast, for it is the number of man: His Number is 666
