"In the visions of the prophet, those who have triumphed over sin and the grave are now seen happy in the presence of their Maker, talking freely with Him as man talked with God in the beginning. “Be ye glad,” the Lord bids them, “and rejoice forever in that which I create: for, behold, I create Jerusalem a rejoicing, and her people a joy. And I will rejoice in Jerusalem, and joy in My people: and the voice of weeping shall be no more heard in her, nor the voice of crying.” “The inhabitant shall not say, I am sick: the people that dwell therein shall be forgiven their iniquity.” PK 729.1"
"And God shall wipe away all tears from their eyes; and there shall be no more death, neither sorrow, nor crying, neither shall there be any more pain: for the former things are passed away."
While EGW quotes Isaiah 65:18-19, the overall theme of no more weeping and the absence of sickness strongly echoes Revelation 21:4. The connection is more than just thematic; it's a shared vision of the future.
"“In the wilderness shall waters break out, And streams in the desert. And the parched ground shall become a pool, And the thirsty land springs of water.” PK 729.2"
"Then shall the lame man leap as an hart, and the tongue of the dumb sing: for in the wilderness shall waters break out, and streams in the desert."
EGW directly quotes Isaiah 35:6.
"“Instead of the thorn shall come up the fir tree, And instead of the brier shall come up the myrtle tree.” PK 729.3"
"Instead of the thorn shall come up the fir tree, and instead of the brier shall come up the myrtle tree: and it shall be to the Lord for a name, for an everlasting sign that shall not be cut off."
EGW directly quotes Isaiah 55:13.
"“And an highway shall be there, and a way, And it shall be called The way of holiness; The unclean shall not pass over it; But it shall be for those: The wayfaring men, though fools, shall not err therein.” PK 729.4"
"And an highway shall be there, and a way, and it shall be called The way of holiness; the unclean shall not pass over it; but it shall be for those: the wayfaring men, though fools, shall not err therein."
EGW directly quotes Isaiah 35:8.
"As the prophet beholds the redeemed dwelling in the City of God, free from sin and from all marks of the curse, in rapture he exclaims, “Rejoice ye with Jerusalem, and be glad with her, all ye that love her: rejoice for joy with her.” PK 729.6"
"Rejoice ye with Jerusalem, and be glad with her, all ye that love her: rejoice for joy with her, all ye that mourn for her:"
The EGW passage directly quotes Isaiah 66:10. This is a clear and explicit allusion.
