Revelation 22:6–13 moves on from the description of life in New Jerusalem (Revelation 21:9—22:5) and focuses on Jesus’ return. This marks the end of John’s visions of the future, returning to more immediate instructions for Christian believers; this is the epilogue to the book of Revelation. Both the beginning and closing of Revelation offer a blessing (Revelation 1:3; 22:7). Both stress the importance of keeping the prophecy being given (Revelation 1:3; 22:7). And both identify Jesus as the Alpha and Omega (Revelation 1:8; 22:13).
