Health is recovered and preserved through obedience to divine natural laws, and destructive habits undermine physical, mental, and spiritual well-being.

Original passage

The physician should teach his patients that they are to cooperate with God in the work of restoration. The physician has a continually increasing realization of the fact that disease is the result of sin. He knows that the laws of nature, as truly as the precepts of the Decalogue, are divine, and that only in obedience to them can health be recovered or preserved. He sees many suffering as the result of hurtful practices who might be restored to health if they would do what they might for their own restoration. They need to be taught that every practice which destroys the physical, mental, or spiritual energies is sin, and that health is to be secured through obedience to the laws that God has established for the good of all mankind.
