"Within the city we saw the tree of life and the throne of God. Out of the throne came a pure river of water, and on either side of the river was the tree of life. On one side of the river was a trunk of a tree, and a trunk on the other side of the river, both of pure, transparent gold. At first I thought I saw two trees; I looked again, and saw that they were united at the top in one tree. So it was the tree of life on either side of the river of life. Its branches bowed to the place where we stood; and the fruit was glorious, which looked like gold mixed with silver. 1T 61.1"
"And he shewed me a pure river of water of life, clear as crystal, proceeding out of the throne of God and of the Lamb."
The EGW passage directly references and expands upon the imagery of the river of water proceeding from the throne of God, as described in Revelation 22:1. The shared elements are too specific to be coincidental.
"In the midst of the street of it, and on either side of the river, was there the tree of life, which bare twelve manner of fruits, and yielded her fruit every month: and the leaves of the tree were for the healing of the nations."
The EGW passage directly references and expands upon the imagery of the tree of life on either side of the river, as described in Revelation 22:2. The shared elements are too specific to be coincidental.
"And when he had taken the book, the four beasts and four and twenty elders fell down before the Lamb, having every one of them harps, and golden vials full of odours, which are the prayers of saints."
Both passages describe heavenly beings with harps. The EGW passage is a clear echo of the imagery in Revelation, even if it's a brief mention.
