"“We wish to call the attention of the brethren everywhere to these works, prepared with especial care, on the important subject of a reform in our manners of life, which is greatly needed, and as we view it, will surely be accomplished in whatever people find themselves at last prepared for translation .“ LS 167.3"
"Then we which are alive and remain shall be caught up together with them in the clouds, to meet the Lord in the air: and so shall we ever be with the Lord."
Both passages discuss the concept of being prepared for translation/being caught up, implying a state of readiness and spiritual refinement. The EGW quote directly links the reform in manners of life to being prepared for translation, which is the same event described in 1 Thessalonians 4:17.
"During the first five months of 1865 this series was completed. These health pamphlets, six in number, contained articles from Mrs. White on “Disease and Its Causes,” and on allied subjects; and many extracts from the writings of various physicians and others interested in health reform principles. Hygienic recipes were included, also hints on the use of water as a remedial agency. The harmful effects of alcohol, tobacco, tea and coffee, spices, and other stimulants and narcotics, were further emphasized. LS 167.4"
"What? know ye not that your body is the temple of the Holy Ghost which is in you, which ye have of God, and ye are not your own? For ye are bought with a price: therefore glorify God in your body, and in your spirit, which are God’s."
The EGW passage promotes health reform principles, aligning with the Bible verse's call to glorify God in one's body, which is considered a temple.
"The winter of 1864-65 was a time of stress and trial. While uniting with his wife in the preparation of matter on health and temperance for publication, Elder White found it necessary to labor untiringly in behalf of Sabbath keepers who were being drafted for service in the army. This work was attended with perplexity and anxiety, and drew heavily on his sympathies, besides overtaxing his physical strength. The administrative cares in the session of the General Conference held in May, 1865, added to his weariness. LS 167.5"
"Beside those things that are without, that which cometh upon me daily, the care of all the churches."
Both passages describe the burden and stress of leadership and responsibility for others. While not a direct quote, the thematic overlap is clear.
