Revelation 22:21

The benediction reminds us that Revelation is a letter, and that its lessons are to be personally appropriated. Only by the grace of the Lord Jesus can that victory be gained which will receive the recompense portrayed in this book. It behoves us to open our lives to it continually, and to add our own Amen.

“Revelation” by George R. Beasley–Murray in New Bible Commentary, p. 1455.
