My point regarding Rev. 20:4 is that these are Christians who obviously co-existed with the Beast, in the Tribulation, at least until the Beast beheaded them.
I always figured that there are some conversions that are going to occur during the tribulation.
To me, if you are giving Satan every possible advantage in the end times, you rapture up the faithful, and leave no saved Christians left on Earth.
Then it begins, the rapture will likely be an “oops” moment for a lot of folks, and there will be more Christians flipping all the way up until the end. In fact, the tighter the squeeze Satan puts on toward the end, the more believers there are likely to be.
It’s a good theory. I have zero to base it on, Biblically.
