Revelation 11:12

12  And they heard a great voice from heaven saying unto them, Come up hither. And they ascended up to heaven in a cloud; and their enemies beheld them.

I am sure the two prophets could have dealt with their enemies at that time but instead they are told to come up to heaven. They are taken from earth so Satan and his angels and his Antichrist can deceive those on earth who did not love the truth and are the enemies of God. Perhaps the Beast will say that their rising from the dead fulfilled the prophecy that the Beast and False Prophet will be cast  alive  into the Lake of Fire and that is where he sent them.

Satan and his angels will be given almost total control of the earth for the next 3 ½ years. Few have any idea about what this all entails. It will not just be one or two men with supernatural powers telling the world what to do. It will be someone who claims to be God and he, like God, will have millions of angels at his immediate command. The fallen angels that are cast out with Satan will enforce his decrees on the earth. It will be as if a superhuman race has come to earth from another dimension or from space and has set up control over the earth. The only place they will not control is the area in the mountains of Jordan that the archangel Michael is protecting for the faithful remnant of Israel.

They may even package the deception as a war between a controlling alien God in heaven who put the Jews on the earth to control it and the God who has come to earth to save mankind from their control (this, believe it or not, is already a new age concept). In any case, those who think they will not be deceived and that they can actually fight such supernatural forces with local militias or by physical resistance will have a reality check that they will not be able to cash.
