Revelation 1:18-20

18I am the Living One; I was dead, and now look, I am alive for ever and ever! And I hold the keys of death and Hades.

19“Write, therefore, what you have seen, what is now and what will take place later.

20The mystery of the seven stars that you saw in my right hand and of the seven golden lampstands is this: The seven stars are the angels of the seven churches, and the seven lampstands are the seven churches.
