Revelation 2:1-11 begins the message to the seven churches. The first two are: Ephesus, the church that lost its first love; Smyrna, the church that stood firm even when it was persecuted; These can be seen as seven historical churches, which they were, but also as seven types of churches as they exist today and through history.
