"Christ never worked a miracle except to supply a genuine necessity, and every miracle was of a character to lead the people to the tree of life, whose leaves are for the healing of the nations. The simple food passed round by the hands of the disciples contained a whole treasure of lessons. It was humble fare that had been provided; the fishes and barley loaves were the daily food of the fisher folk about the Sea of Galilee. Christ could have spread before the people a rich repast, but food prepared merely for the gratification of appetite would have conveyed no lesson for their good. Christ taught them in this lesson that the natural provisions of God for man had been perverted. And never did people enjoy the luxurious feasts prepared for the gratification of perverted taste as this people enjoyed the rest and the simple food which Christ provided so far from human habitations. DA 366.1"
"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 references the 'tree of life, whose leaves are for the healing of the nations' from Revelation 22:2, making it an explicit allusion.
"But he answered and said, It is written, Man shall not live by bread alone, but by every word that proceedeth out of the mouth of God."
The EGW passage discusses the importance of simple food and avoiding the gratification of appetite, which aligns with the principle in Matthew 4:4 that humans need more than just physical sustenance. It's a thematic parallel, though not a direct reference.
