What is the biblical basis for a one world religion in the end times? I was just reading about eschatology and somebody was stating that this verse suggests that there will be a one world religion, a false religion:


  Revelation 17:1–18 (ESV)
  
  1 Then one of the seven angels who had the seven bowls came and said
  to me, “Come, I will show you the judgment of the great prostitute who
  is seated on many waters, 2 with whom the kings of the earth have
  committed sexual immorality ...


Where is support for this concept found in other scriptures?
There's a lot of discussion and debate about this especially due to the nature of the end-time prophecies, but one verse that does back a one world religion at least implicitly.


  Rev 13:8
  
  And all the people who belong to this world worshiped the beast. They
  are the ones whose names were not written in the Book of Life before
  the world was made—the Book that belongs to the Lamb who was
  slaughtered


If everyone is worshiping the "beast" then in essence the religion is the same, whether it is actually one religion or not.
