"In the Revelation are portrayed the deep things of God. The very name given to its inspired pages, “the Revelation,” contradicts the statement that this is a sealed book. A revelation is something revealed. The Lord Himself revealed to His servant the mysteries contained in this book, and He designs that they shall be open to the study of all. Its truths are addressed to those living in the last days of this earth's history, as well as to those living in the days of John. Some of the scenes depicted in this prophecy are in the past, some are now taking place; some bring to view the close of the great conflict between the powers of darkness and the Prince of heaven, and some reveal the triumphs and joys of the redeemed in the earth made new. AA 584.1"
"The Revelation of Jesus Christ, which God gave unto him, to shew unto his servants things which must shortly come to pass; and he sent and signified it by his angel unto his servant John:"
EGW directly references and interprets Revelation 1:1, emphasizing that the book is a revelation meant to be understood, not a sealed book.
"And he said, Go thy way, Daniel: for the words are closed up and sealed till the time of the end."
EGW contrasts the idea of Revelation being open for understanding with the concept of a sealed book, directly alluding to the idea of Daniel 12:9, where the words are sealed until the time of the end. She argues that Revelation is not meant to be sealed in the same way.
"Let none think, because they cannot explain the meaning of every symbol in the Revelation, that it is useless for them to search this book in an effort to know the meaning of the truth it contains. The One who revealed these mysteries to John will give to the diligent searcher for truth a foretaste of heavenly things. Those whose hearts are open to the reception of truth will be enabled to understand its teachings, and will be granted the blessing promised to those who “hear the words of this prophecy, and keep those things which are written therein.” AA 584.2"
"Blessed is he that readeth, and they that hear the words of this prophecy, and keep those things which are written therein: for the time is at hand."
EGW directly quotes Revelation 1:3, emphasizing the blessing promised to those who study and heed the prophecies within the book.
"But the Comforter, which is the Holy Ghost, whom the Father will send in my name, he shall teach you all things, and bring all things to your remembrance, whatsoever I have said unto you."
Both passages speak of the Holy Spirit guiding believers to understand spiritual truths. However, the EGW passage focuses specifically on understanding Revelation, while the John passage is broader. The connection is thematic, but not a direct allusion.
