Revelation opens by calling itself "the revelation of Jesus Christ," given by God to show his servants what must soon take place Revelation 1:1. It also says Jesus made it known by sending his angel to John Revelation 1:1.
Revelation 1:1–3 introduces the book as a message from God, conveyed through Jesus and an angel to John, meant for God’s servants. John’s role is to report what he saw and to pass on God’s word and Jesus’ testimony. These verses function as the book’s opening framing, telling readers what kind of writing this is and how it should be received. The passage sets up a chain of communication—God to Jesus to an angel to John to the servants—so the audience knows the message’s origin and intended recipients.
Revelation opens by identifying its message as a disclosure tied to Jesus Christ, originating with God and intended for God’s servants (verse 1). The passage stresses an ordered delivery channel: God gives it to Jesus, Jesus sends it, an angel communicates it, and John passes it on (verse 1).
A careful answer keeps the immediate passage, the book's argument, and the whole-Bible storyline together, so the question is answered in context instead of as a detached idea.
