The revelation given by Jesus Christ, which God granted Him, that He might make known to His servants certain events which must shortly come to pass: and He sent His angel and communicated it to His servant John.

This is the John who taught the truth concerning the Word of God and the truth told us by Jesus Christ-- a faithful account of what he had seen.

John sends greetings to the seven Churches in the province of Asia. May grace be granted to you, and peace, from Him who is and was and evermore will be; and from the seven Spirits which are before His throne;

I John, your brother, and a sharer with you in the sorrows and Kingship and patient endurance of Jesus, found myself in the island of Patmos, on account of the Word of God and the truth told us by Jesus.

I John heard and saw these things; and when I had heard and seen them, I fell at the feet of the angel who was showing me them--to worship him.
