The first verse of chapter four prepares the reader for the fact that a corner has been turned in the book. We are about to embark on a new section of this unfolding revelation: Revelation 4:1 - "After this I looked, and behold, a door standing open in heaven! And the first voice, which I had heard speaking to me like a trumpet, said, "Come up here, and I will show you what must take place after this."
I think it's very important to understand the purpose of chapters four and five of Revelation. Actually, they don't so much contain the action of the story as they paint the background or setting of the action that is about to take place. In other words, if the rest of the book of Revelation represents the play itself, these fourth and fifth chapters are more like the stage or the set where the play takes place.
There is an understanding, a perspective, that the Spirit of God wants to have settle on our hearts in the study of these two chapters. And I hope to show that this perspective is important for all Christians, at all times. In other words, while these chapters are very important for those of us studying the end of time, they were also important for John and the early Christians as well.
