I was scoffing about the Mark of the Beast because of taking Revelation literally, and it may yet get to that. The forehead or hand thing. But this is definitely part of it.
But in doing so we shouldn't lose sight of sticking to the core principles of those teachings when they happen right in plain sight. So even if the mark of the beast is something else completely different from vax passports, will happen later, or (as I think it is) is more of a creed than an actual mark, we should still operate faithfully when we have little "marks" the worldly people demand we put on.
So even if the mark of the beast isn't the requirement of some states that all obgyn's perform abortions, people in that industry should stick to Christian values as though it is the mark and we are living in the end times. Likewise with a work requirement that you pledge your allegiance to LGBTQPEDO, etc.
It does two things. A: It makes it harder to implement a real mark of the beast policy if we Christians stand our ground on the little marks policies, and B: they are like warm ups for us Christians to prepare us to stick to Jesus if we're living during the real mark of the beast persecution times.
