Revelation says “yes” as well as “no” to the world. The church that is both in and out of Babylon will not be able to sit still. Perceiving idolatry leads us to evangelize. Perceiving injustice leads us to action. “No one can enter imaginatively into the world narrated by this book and remain complacent about things as they are in an unjust world.”11 Both are needed, and both are rooted in Revelation’s final, hopeful vision.
