“That ancient serpent called the devil, or Satan, who leads the whole world astray.” Chapter 12 marks the beginning of John’s fourth vision, the vision of the seven visions. There is no formal introduction to this vision as there was at the beginning of the last two. Still, the subject matter makes it clear that a transition from the events at the close of the last chapter has occurred. It is important to note this transition so that we understand the time frame in which the visions take place.
