I think most anyone reading Revelation sees that it takes a turn in chapter 13

What stays the same: the dragon (Satan) is still here
- at least at the start – and he’s continuing his fight against God
What changes: the dragon, after being defeated three times in the previous chapter
- now scores a significant victory
- also, prior to this, his battle has been in the religion arena
• he tried to sabotage the life and ministry of Jesus
• but now he changes the battlefield and his strategy
