“Write, therefore, what you have seen, what is now and what will take place later. The 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.” Revelation 1:19-20
God wants us to know what to expect in the future. Even though much of Revelation is symbolic and allegorical, the overall message is: Christ is victorious. He controls the future and nothing happens without his permission. Evil will not have the final word.
