"Now Christ again appears to the view of His enemies. Far above the city, upon a foundation of burnished gold, is a throne, high and lifted up. Upon this throne sits the Son of God, and around Him are the subjects of His kingdom. The power and majesty of Christ no language can describe, no pen portray. The glory of the Eternal Father is enshrouding His Son. The brightness of His presence fills the City of God, and flows out beyond the gates, flooding the whole earth with its radiance. GC 665.1"
"And immediately I was in the spirit: and, behold, a throne was set in heaven, and one sat on the throne."
The EGW passage describes Christ on a throne above the city, which aligns with the imagery of Revelation 4:2, where a throne is set in heaven. While Revelation 4 provides more detail, the core image of a throne is present in both.
"is ended, their victory won. They have run the race and reached the prize. The palm branch in their hands is a symbol of their triumph, the white robe an emblem of the spotless righteousness of Christ which now is theirs. GC 665.2"
"After this I beheld, and, lo, a great multitude, which no man could number, of all nations, and kindreds, and people, and tongues, stood before the throne, and before the Lamb, clothed with white robes, and palms in their hands;"
Both passages describe a multitude with white robes and palms in their hands, symbolizing victory and righteousness. EGW explicitly connects the white robe to the righteousness of Christ, amplifying the symbolism found in Revelation 7:9.
"Know ye not that they which run in a race run all, but one receiveth the prize? So run, that ye may obtain."
Both passages discuss a race and a prize, though EGW expands on the symbolism of the palm branch and white robe. The connection is more than just a superficial overlap.
"The redeemed raise a song of praise that echoes and re-echoes through the vaults of heaven: “Salvation to our God which sitteth upon the throne, and unto the Lamb.” Verse 10 . And angel and seraph unite their voices in adoration. As the redeemed have beheld the power and malignity of Satan, they have seen, as never before, that no power but that of Christ could have made them conquerors. In all that shining throng there are none to ascribe salvation to themselves, as if they had prevailed by their own power and goodness. Nothing is said of what they have done or suffered; but the burden of every song, the keynote of every anthem, is: Salvation to our God and unto the Lamb. GC 665.3"
"And cried with a loud voice, saying, Salvation to our God which sitteth upon the throne, and unto the Lamb."
EGW directly quotes Revelation 7:10.
"And every creature which is in heaven, and on the earth, and under the earth, and such as are in the sea, and all that are in them, heard I saying, Blessing, and honour, and glory, and power, be unto him that sitteth upon the throne, and unto the Lamb for ever and ever."
Both passages describe a scene of universal praise to God and the Lamb in heaven. While EGW quotes Revelation 7:10, the broader context of Revelation 5:13, with its emphasis on every creature praising God and the Lamb, is also relevant.
