[The church of Jesus Christ is not silenced] That is, until the very, very end.
The beast that ascendeth out of the bottomless pit shall make war against them, and shall overcome them, and kill them. And their dead bodies shall lie in the street of the great city, which spiritually is called Sodom and Egypt, where also our Lord was crucified. Revelation 11:7b-Revelation 11:8, KJV
The beast coming out of the bottomless pit is the Antichrist and his anti-Christian kingdom. The war he makes against the two witnesses is the persecution that we already described at the end of Revelation 13:1–18. Throughout all the age of the New Testament, though she is persecuted, the church is not silenced. But at the very end, under this anti-Christian kingdom, the two witnesses are finally killed. That doesn't mean that there are going to be no more believers on the face of the earth at this time at all. There will be believers all the way till the very, very end. But it does mean that as an official body, as a true institute, a public organization, the church of Jesus Christ on earth will be snuffed out.
The official ministry of the Word that shines the light of the truth and the witness of the believers fed by that official ministry – the true church as an institution – will not exist during the final, final parts of the reign of the Antichrist. She will have been killed. She will not be able to exist publicly, outwardly, anywhere upon the face of the entire earth. Her office-bearers, and her members too, will not receive the mark of the beast, and therefore she will not be allowed to exist as an institution in society any longer. She will be declared public enemy number one by this kingdom – the greatest threat to the accomplishment of man’s depraved utopia. The church’s office-bearers especially will receive the brunt of the persecution. They will be pursued and they will be killed. And though there are believers, the official witness of the church will be silenced in all the earth. The two witnesses are dead.1
