I'm just a simple old time trader. Made my bones in the belly pit. Being a retail stock jock just wasn't my cup of tea and if I wasn't the world's worst lawyer, I was well in the running for the title.
So, eschatology really isn't my strong suit. However, Revelations 14:9 fairly well defines it and/or sets it out.
"And the third angel followed them, saying with a loud voice, If any man worship the beast and his image, and receive his mark in his forehead, or in his hand,"
Therefore, it appears that one need worship the beast and its image along with receiving the beast's mark.
How loosely we interpret "worship" and "image" would be subject to debate. It doesn't seem as if some vaccine, that makes it more likely than less, to contract some virus .... isn't really worshipping the beast and its image.
But, I'm known to be wrong more often that right ... Unless it comes to fine side-by-side fowling pieces. I'm rarely wrong when it comes to them.
