The seven lampstands which John saw in his first vision are revealed to be seven churches to whom John will now write (see Revelation 1:20) on behalf of Jesus. These letters ground the revelation of Jesus firmly in the life of the church! This is not Jesus in the abstract, it is Jesus revealed in and through his work in and his words to his churches. No individual church is held up as the paradigm for believers everywhere. It is in the seven churches, the larger constellation of congregations, that Christ and his work is more fully revealed.
In the letters we get a description of the churches through Jesus’ eyes. The things important to Jesus are revealed in these letters. So let’s read between to find out what it is that interests/concerns Jesus.
