"Now was seen the application of those words of Christ in the Revelation, addressed to the church at this very time: “These things saith He that is holy, He that is true, He that hath the key of David, He that openeth, and no man shutteth; and shutteth, and no man openeth; I know thy works: behold, I have set before thee an open door, and no man can shut it.” Revelation 3:7, 8 . GC 430.1"
"And to the angel of the church in Philadelphia write; These things saith he that is holy, he that is true, he that hath the key of David, he that openeth, and no man shutteth; and shutteth, and no man openeth;"
EGW directly quotes Revelation 3:7, 8 and explicitly states its application.
It is those who by faith follow Jesus in the great work of the atonement who receive the benefits of His mediation in their behalf, while those who reject the light which brings to view this work of ministration are not benefited thereby. The Jews who rejected the light given at Christ's first advent, and refused to believe on Him as the Saviour of the world, could not receive pardon through Him. When Jesus at His ascension entered by His own blood into the heavenly sanctuary to shed upon His disciples the blessings of His mediation, the Jews were left in total darkness to continue their useless sacrifices and offerings. The ministration of types and shadows had ceased. That door by which men had formerly found access to God was no longer open. The Jews had refused to seek Him in the only way whereby He could then be found, through the ministration in the sanctuary in heaven. Therefore they found no communion with God. To them the door was shut. They had no knowledge of Christ as the t…
"He came unto his own, and his own received him not."
The EGW passage discusses the Jews rejecting Christ and thus not receiving pardon, which directly echoes the sentiment in John 1:11. The theme of rejection and its consequences connects the two passages.
"Neither by the blood of goats and calves, but by his own blood he entered in once into the holy place, having obtained eternal redemption for us."
The EGW passage discusses Jesus entering the heavenly sanctuary with his own blood, which is a clear parallel to Hebrews 9:12. The context of atonement and access to God connects the two.
"The condition of the unbelieving Jews illustrates the condition of the careless and unbelieving among professed Christians, who are willingly ignorant of the work of our merciful High Priest. In the typical service, when the high priest entered the most holy place, all Israel were required to gather about the sanctuary and in the most solemn manner humble their souls before God, that they might receive the pardon of their sins and not be cut off from the congregation. How much more essential in this antitypical Day of Atonement that we understand the work of our High Priest and know what duties are required of us. GC 430.3"
"And he shall make an atonement for the holy place, because of the uncleanness of the children of Israel, and because of their transgressions in all their sins: and so shall he do for the tabernacle of the congregation, that remaineth among them in the midst of their uncleanness."
Both passages discuss the Day of Atonement and the need for the people to humble themselves and seek atonement. EGW draws a parallel between the ancient Israelite practice and the need for Christians to understand and participate in Christ's work as High Priest.
