Letters to 7 Churches

The book of Revelation in the New Testament is a record of end time events leading up to the return of Jesus Christ.
This is a record of a vision that Apostle John received while he was in the lonely island of Patmos.
There, Jesus Christ appeared to John and instructed him to: "Write on a scroll what you see and send it to the seven churches: to Ephesus, and to Smyrna, and to Pergamum, and to Thyatira, and to Sardis, and to Philadelphia, and to Laodicea.”
These seven churches were seven local congregations of early Christians living in each city.
The seven Churches are named for their locations.
All of them are located in the Asia Minor, present-day Turkey.
The order of these cities corresponds to the route along which a courier from Patmos would have carried the scroll.
