Bible-beliving Christians left behind by the rapture who refuse the loyalty mark/GPS chip will be treated as having mental deficiencies (a new psychiatric term may be invented to describe them). Then, when plagues, etc. begin to be poured out on the earth, the Christians will be blamed, and they will be called "anti-social, anti-harmony, anti-peace" and persecuted.

Evidence will point to vials of viruses/bacteria being smuggled from the Centers for Disease Control and Prevention or other storage facilities. And the fact that Christians do not suffer from some of the plagues/boils that affect non-Christians will be pointed out, as they demand the antidote that they accuse Christians of hiding.......You may even see amazing new "alien" technologies used to hunt people down, and you may even see "aliens" (demons) used to make war against those who refuse to submit to the antichrist.
