You can’t really cite a prophesy that says there will be coming one world religion. You are, of course, relying on the Mystery Babylon riding the Beast, but that could just as easily be a dominant occult religion and not a one world religion.
After all, there will be unraptured new believers in Jesus at that time, who believe after the rapture, so ‘one world religion’ is not true just because of the presence of these believers in Jesus. That equals at least two religions.
Revelation 6:10and they cried out with a loud voice, saying, "How long, O Lord, holy and true, will You refrain from judging and avenging our blood on those who dwell on the earth?" 11And there was given to each of them a white robe; and they were told that they should rest for a little while longer, until the number of their fellow servants and their brethren who were to be killed even as they had been, would be completed also.
Now how many religions are left?
