Charles Ellicott Commentary Revelation 22:7

"And behold, I come quickly. Blessed is he that keepeth the words of the prophecy of this book." — Revelation 22:7 (ASV)

Behold, I come quickly.—The words of Christ Himself follow (perhaps quoted by the angel), to confirm the declaration of the last verse. These confirming words are an embodiment of the spirit of the whole Apocalypse. And behold I am coming quickly! The Apocalypse is the revelation of the coming One; it reveals the dealings of Him who came, who comes, and is to come. (Compare Note on Revelation 1:4.) The blessing given in Revelation 1:3 is in part repeated here, but it is a benediction emphatically on those who keep the words of the book.

Blessed is he who keepeth the words of the prophecy of this book. It is not in reading, or wondering, or talking, but in keeping, that the blessing comes. He who loves Christ will keep His commandments (John 14:15), even as Christ loved His Father, and kept His commandments (John 15:10). Those who so keep the sayings or words of Christ in this book will stand firm as those who have built upon the rock (Matthew 7:24–25). The blessing of Christ to such was victory over death. If a man keep My saying, he shall never see death (John 8:51).
