If people were asked regarding which was the most confusing book of the Bible, it is likely that most would say it was the Book of Revelation. Yet we can see from the prologue to the book that there is a blessing attached to it.
The originator of the book is God the Father, who gave it to Jesus, who then gave it through an angel to the apostle John. Since the book comes from the Father, we should deduce that it is a family book for his children. He sent it for their encouragement and comfort, and I would suggest that he wanted them to have comfort for four reasons.
The first was the role that Jesus has as the Mediator in the working out of God’s purpose; the second is that God the Father is fully aware of their current circumstances (and by implication, the circumstances of his people in any period); the third is that they will face powerful opponents who cannot defeat him; and the fourth is that eventually they will have a wonderful future in a new world.
The Father gave the details to Jesus after he had returned to heaven. This description of Jesus as the recipient of revelation from the Father does not highlight a weakness in him or a deficiency in his person. He always is the eternal Son of the Father. Instead, it points to the great dignity that has been given to him as the exalted Saviour. Jesus as the Mediator understands the descriptions of himself in this book and as the Mediator he has the ability to achieve what is said about him.
So if we want to know about Jesus, the Book of Revelation is a book to read. If we want to know about life on earth for the people of God, the Book of Revelation is a book to read. And if we want to know about the endless prospects of the church, the Book of Revelation is a book to read.
