“When we live in a world of violence long enough, it is easy to adopt violent means ourselves, especially when we know that our cause is righteous and the opposition is evil. Religious faith, especially when zealous, is no stranger to the exercise of violent force. And so St. John, having set down his counsel to endure, yokes it with a warning to not defect into violence. That would be just as bad as defecting into cowardly compliance. Had not Jesus, in as violent a scene as any of us will find ourselves, said, ‘Put your sword back into its place; for all who take the sword will perish by the sword’? (Matt. 26:52). Killing the opposition is the sea beast’s [Revelation 13:1-10] way of solving its problems. It is not ours. Our is endurance and faith.
“This combination, endurance and faith, is not dumb passivity … The Christ-followers had learned something profound about sacrifice and death: endurance and faith are aggressive forces in the battle raging between God and the devil. It requires high energy to meet the sword with willed suffering, with embraced sacrifice.”
