"Feebler and still feebler grew the physical frame; but the spirit was courageous ever. In conversation with Dr. David Paulson on January 25, 1915, Mrs. White said: “The Lord has been my helper, the Lord has been my God, and I have not a doubt. If I could not realize that He has been my guide and my stay, do tell me what I could trust in. Why, I have just as firm a trust in God that He will stand my feet on Mount Zion, as that I live and breathe; and I am going to keep that trust till I die.” LS 442.1"
"My flesh and my heart faileth: but God is the strength of my heart, and my portion for ever."
Both passages deal with physical weakness contrasted with spiritual strength and trust in God. EGW's statement about trusting God to stand her feet on Mount Zion despite her failing health directly parallels the sentiment in Psalm 73:26.
"The Lord is my rock, and my fortress, and my deliverer; my God, my strength, in whom I will trust; my buckler, and the horn of my salvation, and my high tower."
Both passages express trust in God as a source of strength and security, particularly in times of weakness or uncertainty. EGW's statement echoes the sentiment of reliance on God found in Psalm 18:2.
