The letters to the pastors of the seven churches in Asia are a prophecy of the history of the Church, according to dispensationalist Bible teachers. For interpreters who are committed to a “literal” hermeneutic, this is bending the rules in the direction of a “literary” hermeneutic, which is excellent. However, they apply the letters to the wrong future, and overlook the obvious allusions to the past.
According to James Jordan, the seven churches are presented as a sort of “decentralized” menora, that is, seven lamps instead of a single seven-branched lampstand. Once this way of thinking is pointed out, it amazes me how much of what is obvious in the text we miss entirely.
This image suggests that we are supposed to take the Church as a new Israel, a conclusion which would not be so popular with dispensationalists, but one that seems unavoidable. The Bible teaches “replacement theory,” or at least, “transformation theory.” Like Jesus, Israel was about to pass through death and resurrection and come out of the grave renewed and as different from old Israel as a butterfly is from a caterpillar.
The Romans would remove the Lampstand from Herod’s Temple, as is predicted later in the Revelation (18:23). The new “decentralized” worship would not be centered on earth but in heaven, on the true Zion (Paul says as much in Galatians 4).
Further support is found in the fact that the seven letters are a brief retelling of Old Israel’s history (following Israel’s festal calendar). Once this is observed, the use of the names of Old Testament characters suddenly makes perfect sense.
Following the seven letters, the rest of the Book of Revelation is an eighth letter, John’s “little book.”  The budding sins which Jesus critiques in the fledgling church are shown to be full grown in the worship in Jerusalem (the harlot and false prophet are a Jewish Jezebel and Jewish Balaam, ruling and cursing Jerusalem). The Lampstand was made to look like an almond tree, literally a “watcher tree.”
The word of the LORD came to me saying, “What do you see, Jeremiah?” And I said, “I see a rod of an almond tree.” (Jeremiah 1:11)
These New Covenant “watchmen” watch on as she is destroyed. So, the letters are a prophecy of future Church history, but a history of the “Firstfruits” Church, leading up to AD70, with only a brief glimpse of “the age to come” in chapter 20.
The meanings of the names of the cities also seem significant in identifying the “dominion” pattern:
As Jordan observes, the Church pastors are the seven stars in Jesus’ right hand. Jesus is the new Tabernacle, and His right hand is the new Lampstand, one whose light multiplies and reaches every corner of the earth.
