The following is a helpful statement that helps capture his overall approach to martyrdom in the Apocalypse: "[w]hen the whole Apocalypse has been heard, it will be clear that suffering for the faith involves many things before death. But the witnessing church is first and foremost identified collectively as a martyr church, patterned after the martyr status of the Lamb." Pattemore, therefore, seems to give due weight to the theme of martyrdom and the larger theme of "witnessing to the testimony of Jesus." I especially think the final sentence captures well what one encounters in the Apocalypse. As one reads, one gets the sense that John is developing an idealic picture of the church as a collective group of martyrs. I prefer to think of this as somewhat of a "rhetorical device" (I'm sure there is a more apt description) that aims to present martyrdom as "the normal Christian life."
That said, here is a link to the story of a man who "lived out" the message of the Apocalypse.
