A First Century Message to Twentieth Century Christians 

In order to a proper understanding of the purpose of the letters to the churches of Asia, it is necessary that some word should be spoken concerning the book in which they are to be found.

This book contains the last messages of Christ to men. In some important ways it differs from any other in the Divine Library. John did not receive it by the inspiration of the Spirit in the ordinary sense of that expression, but directly from Jesus Christ, as He appeared to him while in exile in Patmos.
