10 On the Lord’s Day I was in the Spirit, and I heard behind me a loud voice like a trumpet, 11 which said: “Write on a scroll what you see and send it to the seven churches: to Ephesus, Smyrna, Pergamum, Thyatira, Sardis, Philadelphia and Laodicea.” 12 I turned around to see the voice that was speaking to me. And when I turned I saw seven golden lampstands, 13 and among the lampstands was someone like a son of man, dressed in a robe reaching down to his feet and with a golden sash around his chest.
This article at turkeytourorganizer.com, a travel website, addresses the background of these churches in this verse and also has a picture of some architectural ruins from each city in which the churches were located, so it gives us a little bit of visual material to meditate on while thinking about each church that received a copy of John's writings.
John refers to being "in the spirit" in verse ten of this chapter; the writer of this article at preachitteachit.org postulates different theories as to what that might mean.
When I looked up the significance of the golden sash Jesus is wearing in these verses I found this article at hello-bible.com that compares this verse with other biblical prophecy and points to beautiful verses in Daniel that contain a very similar version of a vision of Jesus in which He also wears the golden sash; these verses are from Daniel 10:5-12
