Hi David, that is the verse.
"Are become" because, at the time of the 7th angel/third woe, God asserts His power in verse 17, to take those kingdoms out from under the rule of Satan and his angels kingdom of Mystery, Bablyon the Great. Destroying Satan's kingdom takes place over a time, times, half time period.
Douggg, speaking of a time, times, half time period, I would think the following is fulfilled during that period. And I'm sure you at least agree with that.
Revelation 13:4 And they worshipped the dragon which gave power unto the beast: and they worshipped the beast, saying, Who is like unto the beast? who is able to make war with him?
5 And there was given unto him a mouth speaking great things and blasphemies; and power was given unto him to continue forty and two months.
6 And he opened his mouth in blasphemy against God, to blaspheme his name, and his tabernacle, and them that dwell in heaven.
7 And it was given unto him to make war with the saints, and to overcome them: and power was given him over all kindreds, and tongues, and nations.
8 And all that dwell upon the earth shall worship him, whose names are not written in the book of life of the Lamb slain from the foundation of the world.
If the 7th trumpet has already sounded prior to these events, why is the question being posed in verse 4---Who is like unto the beast? who is able to make war with him?
You would think Christ should be the one able to make war with him at the time, yet verse 7 shows this instead----And it was given unto him to make war with the saints, and to overcome them: and power was given him over all kindreds, and tongues, and nations.
All of this contradicts Revelation 11:15 if Revelation 11:15 is fulfilled prior to the events recorded in Revelation 13:4-8, rather than after those events instead. The 7th trumpet is at the end of a time, times, and half a time, and not prior to or at the beginning of it instead. Revelation 11:19, the last verse in that chapter, tends to prove we are in the time of the vials of wrath once the 7th trumpet sounds. Revelation 13:4-8 tends to prove we are not yet in the time of the vials of wrath during what is recorded in those verses. No one could possibly be saying during the vials of wrath, Who is like unto the beast? who is able to make war with him?
BTW, I know we are going to continue to disagree about this in particular until the cows come home. I'm seeing nothing but contradictions in the texts involved if Revelation 11:15 is not meaning after the 42 month reign of the beast.
