D. The final benediction 22:21

This benediction wishes God's enabling grace on all who read the book.

"As in revelation, so in history: graceshall have the last word!"⁸⁰³

God's grace makes faith, for the unbelieving reader, and faithfulness, for the believing reader, possible (cf. 1:4). This benediction is a prayer that all its hearers and readers may respond to the revelation of this book appropriately. It is an unusual way to end an apocalypse, but it was a common way to close a first-century Christian letter (cf. 1:1).
