"The mystery of the seven stars which
thou sawest in my right hand, and the
seven golden candlesticks.

The seven stars are the angels of the
seven churches: and

the seven candlesticks which thou
sawest are the seven churches."
Revelation 1:20

The seven stars are the angels, the
ministers of these churches.

The candlesticks are the churches with
Jesus Christ walking among them.

They are the light of the world.
