Revelation 12:17

17  And the dragon was wroth with the woman, and went to make war with the remnant of her seed, which keep the commandments of God, and have the testimony of Jesus Christ.

Satan and his angels cannot touch the woman being protected in the mountains of Jordan so he will declare war on all descendants of natural Israel and all who keep the testimony of Jesus Christ all over the earth. This includes those who identified themselves as Christians in the “left behind” apostate World Church who will not renounce Jesus and take the mark of the Beast.

Up until this point the world religion harlot is riding the Beast and controlling the direction of world events but after Satan is cast out to the earth and becomes a counterfeit god  he will turn on the harlot of world religion and burn her with fire. This is spoken about in detail in chapter 17.

Here we see that all who confess Jesus or Jehovah and believe the truths in the Bible will become the targets of Satan.
