"Visit to Indiana August 9-14 I attended the camp meeting in Indiana, accompanied by my daughter, Mary K. White. My husband found it was impossible for him to leave Battle Creek. At this meeting the Lord strengthened me to labor most earnestly. He gave me clearness and power to appeal to the people. As I looked upon the men and women assembled here, noble in appearance and commanding in influence, and compared them with the little company assembled six years before, who were mostly poor and uneducated, I could but exclaim: “What hath the Lord wrought!” 4T 276"
"The Lord hath done great things for us; whereof we are glad."
The EGW passage directly quotes the sentiment of Psalm 126:3, acknowledging God's work and expressing joy. This is a clear and intentional allusion.
