"This temple was supported by seven pillars, all of transparent gold, set with pearls most glorious. The wonderful things I there saw, I cannot describe. Oh, that I could talk in the language of Canaan, then could I tell a little of the glory of the better world. I saw there tables of stone in which the names of the 144,000 were engraved in letters of gold. 1T 69.1"
"Him that overcometh will I make a pillar in the temple of my God, and he shall go no more out: and I will write upon him the name of my God, and the name of the city of my God, which is new Jerusalem, which cometh down out of heaven from my God: and I will write upon him my new name."
Both passages describe elements of the New Jerusalem. Revelation speaks of pillars and writing the name of God on them, while EGW describes pillars in the temple and names engraved on stone. The connection is strong enough to confirm.
After beholding the glory of the temple, we went out, and Jesus left us and went to the city. Soon we heard His lovely voice again, saying: “Come, My people, you have come out of great tribulation, and done My will, suffered for Me, come in to supper; for I will gird Myself and serve you.” We shouted, “Alleluia, glory,” and entered the city. Here I saw a table of pure silver; it was many miles in length, yet our eyes could extend over it. I saw the fruit of the tree of life, the manna, almonds, figs, pomegranates, grapes, and many other kinds of fruit. I asked Jesus to let me eat of the fruit. He said: “Not now. Those who eat of the fruit of this land, go back to earth no more. But in a little while, if faithful, you shall both eat of the fruit of the tree of life and drink of the water of the fountain. And,” said He, “you must go back to the earth again, and relate to others what I have revealed to you.” Then an angel bore me gently down to this dark world. Sometimes I think I can sta…
"And I said unto him, Sir, thou knowest. And he said to me, These are they which came out of great tribulation, and have washed their robes, and made them white in the blood of the Lamb."
EGW directly quotes the phrase 'come out of great tribulation' which is a clear allusion to Revelation 7:14.
"Blessed are those servants, whom the lord when he cometh shall find watching: verily I say unto you, that he shall gird himself, and make them to sit down to meat, and will come forth and serve them."
EGW's passage includes the phrase 'I will gird Myself and serve you,' which is a direct allusion to Luke 12:37.
"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."
Both passages describe the tree of life and its fruit in a heavenly setting. EGW's description elaborates on the types of fruit and the experience of eating it, which aligns with the general theme of abundance and eternal life presented in Revelation 22:2.
