Ezra Taft Benson:
“There is no question that the health of the body affects
the spirit, or the Lord would never have revealed the Word of Wisdom. God has
never given any temporal commandments—that which affects our bodies also
affects our spirits. …
“… Sin debilitates. It affects not only the [spirit], but
the body. The scriptures are replete with examples of the physical power that
can attend the righteous. On the other hand, unrepented sin can diffuse energy
and lead to both mental and physical sickness” (“In His Steps,”Ensign, Sep.
1988, 5).
