"The Earth Desolated My attention was again directed to the earth. The wicked had been destroyed, and their dead bodies were lying upon its surface. The wrath of God in the seven last plagues had been visited upon the inhabitants of the earth, causing them to gnaw their tongues from pain and to curse God. The false shepherds had been the signal objects of Jehovah's wrath. Their eyes had consumed away in their holes, and their tongues in their mouths, while they stood upon their feet. After the saints had been delivered by the voice of God, the wicked multitude turned their rage upon one another. The earth seemed to be deluged with blood, and dead bodies were from one end of it to the other. EW 289"
"And there fell upon men a great hail out of heaven, every stone about the weight of a talent: and men blasphemed God because of the plague of the hail; for the plague thereof was exceeding great."
Both passages describe the effects of God's wrath on the wicked. While Revelation 16:21 specifically mentions hail, EGW's passage describes a more general devastation and suffering, including blasphemy, which aligns with the overall theme of divine judgment in Revelation.
"I then saw Jesus leading His people to the tree of life, and again we heard His lovely voice, richer than any music that ever fell on mortal ear, saying, “The leaves of this tree are for the healing of the nations. Eat ye all of it.” Upon the tree of life was most beautiful fruit, of which the saints could partake freely. In the city was a most glorious throne, from which proceeded a pure river of water of life, clear as crystal. On each side of this river was the tree of life, and on the banks of the river were other beautiful trees bearing fruit which was good for food. EW 289.1"
"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 quotes and elaborates on Revelation 22:2, specifically mentioning the tree of life, its leaves for healing, and the river of water of life. This constitutes a clear and explicit allusion.
"Language is altogether too feeble to attempt a description of heaven. As the scene rises before me, I am lost in amazement. Carried away with the surpassing splendor and excellent glory, I lay down the pen, and exclaim, “Oh, what love! what wondrous love!” The most exalted language fails to describe the glory of heaven or the matchless depths of a Saviour's love. EW 289.2"
"But as it is written, Eye hath not seen, nor ear heard, neither have entered into the heart of man, the things which God hath prepared for them that love him."
Both passages express the inadequacy of human language to describe the glories of heaven and God's love. EGW's passage echoes the sentiment of 1 Corinthians 2:9, which speaks of things beyond human comprehension.
