Why was John on the Island of Patmos? The tribulation was already underway in 95 AD. This teaching tells the story behind the book of Revelation from Roman histories, Church legend, and the Chronicles of the Apostles. The story of the Domitian persecution provides clues to unlock the meaning of the book of Revelation.
I, John, your brother and partner in the tribulation and the kingdom and the patient endurance that are in Jesus, was on the island called Patmos on account of the word of God and the testimony of Jesus. (Revelation 1:9)
