Revelation is God lifting the lid off of Christ, or pulling back the wrapping paper on something very special about Jesus, but not yet fully seen or known. That is what the first word of this book says.
So, chapter 1 is God holding out for us: What Jesus is doing right now.
Chapters 2-3 are God showing us what Jesus sees in His Church.
Chapters 4-22 are what God wants us to know about His plans for the future.
Each of these sections of Revelation is a disclosure and an unveiling of things not yet fully seen, or even really understood.
