That's not going to happen. Historically it's been the exact opposite. Which trials much?
All 50 states have built quarantine centers which can double as concentration camps.
FEMA has purchased tens of thousands of coffin liners which can be used instead of a coffin and can hold several small bodies if necessary.
During the Pandemic the government was able to create a list of every single member of a church that was a member of their facebook page.
The economy is set for when this "Black Swan" event takes place to fully collapse and create a famine forcing people to take their digital currency. We will probably see 80% of those still alive choose to take the mark of the beast so they can continue to buy and sell. However, there will still be 1 billion people who do not do this willingly. They will be rounded up and given the choice between beheading and the mark and it is very likely 80% of those will also choose the mark.
But that still leaves 200 million worldwide that will need to be hunted down. Some will starve, some will be killed, and some will be coerced. But even so, dealing with 100 million Christians, that is a very big job. The Germans exterminated around 10 million. So this will be 10x as a big a job, and you need to search the entire globe.
God is going to make sure every single person makes a choice before the tribulation is over, so they will hunt them down. Satellites, drones, robotic dogs, cyborg military men with the chip in their brain, etc.
