Apostle John recorded Rv 1:1-8 as a summary of Revelation after he saw and heard the events of all the chapters of Revelation. Since Rv 1:3 is part of this summary of Revelation, the three entities mentioned in the title of this article—the one who reads, those who hear, and those who obey (Rv 1:3)—can be found elsewhere in Revelation. Anyone who desires the correct answer to the question in the title should ask Jesus, Apostle John, or the pastor in the position of Apostle John who ate the open book of Revelation in Rv 10 in reality. The one who reads is Apostle John who eats the scroll in 10; those who hear are the nations, peoples, languages, and kings in Rv 10; those who obey are the 144,000 and the great multitude in white robes in Rv 1:1, Rv 7, and Rv 14.
Just as it was prophesied in Ezekiel chapter 1, 2, and 3, Jesus received the revelation (i.e. the revealed word) at the first coming (Mt 11:27) and was then sent to the lost sheep, the rebellious people of Israel of the exile, to proclaim the revealed word (i.e. the revelation) to them.
In a same way, when the Revelation that Apostle John saw in vision comes to fulfill, there will be the pastor who comes in the position of Apostle and eats the revealed scroll and will preach the word to peoples, nations, language, and kings according to Jesus’ commands (Rv 13:7). At a time like this, it is only by seeing, hearing, and believing in the revealed word—it is only by sealing this word in our hearts—that we are able to attain salvation. This is God’s will and God’s way to save us. Today, we in SCJ are testifying, not about visions, but about the physical fulfillment of the prophecies along with the revealed word of the opened book.
