29.

To whom was the book dedicated? “John _to the seven churches which are in Asia_.” Verse 4. 7. What were the names of these seven churches? “What thou seest, write in a book, and send it unto the seven churches which are in Asia; unto _Ephesus_, and unto _Smyrna_, and unto _Pergamos_, and unto _Thyatira_, and unto _Sardis_, and unto _Philadelphia_, and unto _Laodicea_.” Verse 11. NOTE.—These seven churches, and the messages addressed to them, apply to seven periods or states of the church reaching from the first to the second advent of Christ. “Under this emblematical representation of the seven churches of Asia,” says Vitringa, in the “Comprehensive Commentary,” “the Holy Spirit has delineated seven different states of the Christian church, which would appear in succession, extending to the coming of our Lord and the consummation of all things.” Their good qualities and their defects are pointed out, with admonitions, exhortations, and warnings suitable for each, all of which are also applicable to individual Christian experience.
