Howard W. Hunter's Healing — Sustained by Faith in His Final Years

President Howard W. Hunter served as President of the Church for only nine months due to his declining health. Yet in that brief time, he initiated the completion of the Salt Lake Temple and inspired a renewed emphasis on personal temple worship. Despite his physical frailty, Hunter's spiritual strength never wavered. His testimony remained firm, his love for the Savior undimmed, and his faith sustained him through his final illness. His brief but powerful presidency demonstrated that the Lord can accomplish His purposes through faithful servants even when they are physically limited.

Fuller account of this event (as retold in Howard W. Hunter - By Common Consent, a Mormon Blog (2015)):

President Hunter faced many medical problems during his time in Church service, for which he became somewhat known, including a heart attack, broken ribs from a fall at general conference, heart bypass surgery, bleeding ulcers, kidney failure, hospitalization for exhaustion, and finally prostate cancer that spread to his bones in the last few months of his life. He had faced health problems since his earliest childhood when as a four year old — and nearly half a century before the polio vaccine was revealed through painstaking scientific discovery — he suffered from polio, which reportedly affected his back for the rest of his life.
