Then the angel said to me, These words are reliable and true. The Lord, the God of the spirits of the prophets, has sent his angel to show his servants what must happen soon.
7 (Look! I am coming soon! Blessed is the one who keeps the words of the prophecy expressed in this book.)
8 I, John, am the one who heard and saw these things, and when I heard and saw them, I threw myself down to worship at the feet of the angel who was showing them to me. 9 But he said to me, Do not do this! I am a fellow servant with you and with your brothers the prophets, and with those who obey the words of this book. Worship God!
One of the big principles in American law is giving notice. The idea is that you are given adequate knowledge in advance of a needed response or decision you must make. Generally, this advance knowledge and your required actions must be put into writing.
Through John and the angels, God is putting us on notice that obedience and perseverance are required in response to the disclosures God is making to us through his agents. What will you do with the holy summons?
If you analyze this biblical text for frequency, words occurs three times, and the combination prophets-prophecy-prophets also grabs attention. When you combine that knowledge with the statement from Jesus in 22:7 — Blessed is the one who keeps the words of the prophecy expressed in this book — you have to realize that obedience to the challenge to overcome is a crucial theme in Revelation.
Greg Beale says that the purpose of Revelation is to induce obedience among Gods people and supports his statement by pointing out that eight of the final fifteen verses exhort or warn toward that goal. This general theme is stated a little differently by Grant Osborne, who says that perseverance is the primary theme of the book.
When Jesus says that the one who obeys is blessed (22:7), the previous context describing the splendor of the New Jerusalem fills that word with substance that had not previously been revealed.
John again puts considerable emphasis on his own eyewitness testimony (22:8). These visions and words are not idle thoughts or a creation of Johns own mind, and he makes that very clear to his readers.
Understandably, John is once again overcome by what he has seen and heard, and he falls down to worship the angel (22:8). The angel rebukes John in a manner virtually identical to 19:10. Explaining Johns lapse, Osborne says that the two almost identical incidents serve as bookends for the material from 19:11 to 22:5, which includes the end of the former age and the creation of the new heaven and earth. The angel again stresses to John the equality of angels with the saints and prophets who all serve God. Note the particular emphasis on those who obey the words of this book (22:9).
The angels words Worship God! (22:9) do not in this context mean to sing praise songs or any of the other activities normally associated with corporate worship. Instead they mean to worship God by persevering and staying in readiness for the any-moment return of Christ.
To be or not to be?
Osborne makes the telling point that every passage in the NT on the imminent return of Jesus ends with a demand to walk worthily of the Lord because he is coming soon.
The thing is, in an hour from this moment your decisive interview with Jesus may be over!
