"“Facts of Faith” has long been out of print, the matter contained therein having been largely incorporated, with many additions, in the later volume, “Spirit of Prophecy,” Volume 1 (1870), and finally in “Patriarchs and Prophets” (1890). When “Patriarchs” was completed, Mrs. White hoped soon to go on with the story from the close of David's reign, and publish in connected form that which she had been enabled to write through the years concerning the experiences of Solomon and divided Israel, and their final restoration to divine favor as one united people,—a type of spiritual Israel, the church of God on earth today, to whom will finally be fulfilled all the covenant promises. LS 435.2"
"Not as though the word of God hath taken none effect. For they are not all Israel, which are of Israel:"
Both passages discuss the concept of spiritual Israel and the fulfillment of covenant promises. EGW explicitly mentions the restoration of Israel as a type of the church, echoing the idea in Romans 9:6 that not all who are physically Israel are part of spiritual Israel.
