In the book of Revelation, why did Jesus have to die?

This article discusses the significance of Christ’s death as explained by Revelation’s vision of the sealed book. Jesus receives a book that is sealed up with seven seals (Rev 5:7, 1). Before His death, nobody was able to open the book (Rev 5:3) but, after He appeared as a slain lamb, Jesus Christ was declared “worthy” to break the seals (Rev 5:5, 9). So, the purpose of this article is to explain why He was not “worthy” to break the seals before His death and how did His death make Him “worthy?”
