A practicing physician for more than 40 years, Elder Malcolm S. Jeppsen, then of the Seventy, said at the April 1994 general conference that he'd had many occasions to see patients who were sick or who had sustained injuries to their bodies.
"I hereby make an admission: physicians do not cure patients," he said. "This marvelous and complicated machine we call the human body has built into it its own wonderful healing mechanism. All a physician can do is provide a good healing environment."I soon learned in my medical practice that the ultimate healing process for an injured or sick body was already provided by our Heavenly Father. I also learned that a patient's attitude has much to do with healing. Those who would rely on Heavenly Father and exercise faith in the power of the priesthood often enjoyed faster recoveries.
"I have witnessed miracles! Many times when my medical training suggested a dismal prognosis, I have seen individuals fully recover. I have also witnessed others who relied with faith on the Lord and sought blessings with their prayers, which were not answered in a way the person or loved one desired.
"The Lord has given a condition for healing blessings: `He that hath faith in me to be healed, and is not appointed unto death, shall be healed.' (D&C 42:48.) Even when a person relies on faith in the Lord for blessings, if it is his or her appointed time to die, there will not be restoration of health. Indeed, `death [must come] upon all men, to fulfil the merciful plan of the great Creator.' (2 Ne. 9:6.)
President Spencer W. Kimball has written:
"If all the sick for whom we pray were healed, if all the righteous were protected and the wicked destroyed, the whole program of the Father would be annulled. . . . No man would have to live by faith. . . . There would be little or no suffering, sorrow, disappointment, or even death, and if these were not, there would also be no joy, success, resurrection, nor eternal life.' " (Faith Precedes the Miracle [Salt Lake City: Deseret Book Co., 1972], p. 97.)
