I find it preposterous that a silly, man-made mark put on a believer can somehow cancel out Christ’s Salvation that the believer has accepted, and condemn them to Hell.
Technology & Security companies already have technology that they are selling as “smart cities” and “smart homes” that can monitor your every move, adjust your desired thermostat settings, unlock & lock your homes with your biometric ID/password, sense when you are near to unlock and turn your car on - basically run your entire life without a thought.
It’s here. I believe the post rapture world will clamor and demand a secure ID to prevent fraud such as what happened with Equifax and terrorism.
It’s ramping up and up - faster & faster. Keep looking up! We’re going home soon I think.
