If I have read the Word correctly, there will be some who live off grid but finding people will be easy, so by the time the two prophets have been killed and the beast, the dragon, and the false prophet proclaim they are god, there will basically be two choices, die for your faith or become a slave. Either way, overcome and experience the peace on earth promised at His birth.
True. That scenario sounds correct for the times of the Tribulation. I believe in a pre-Tribulation rapture, so I hope not to be around at that point.
