"Chapter 41—The Death of Elder James White Notwithstanding the labors, cares, and responsibilities with which my husband's life had been crowded, his sixtieth year found him active and vigorous in mind and body. Three times had he fallen under a stroke of paralysis; yet by the blessing of God, a naturally strong constitution, and strict attention to the laws of health, he had been enabled to rally. Again he traveled, preached, and wrote with his wonted zeal and energy. Side by side we had labored in the cause of Christ for thirty-five years; and we hoped that we might stand together to witness the triumphant close. But such was not the will of God. The chosen protector of my youth, the companion of my life, the sharer of my labors and afflictions, was taken from my side, and I was left to finish my work and to fight the battle alone. LS 247"
"For which cause we faint not; but though our outward man perish, yet the inward man is renewed day by day."
The EGW passage describes the physical decline and death of James White, while the 2 Corinthians verse speaks of the outward man perishing. While the context is different (one is a specific death, the other a general principle), there's a thematic resonance about physical decline.
