"The condition of the physical body can affect the spirit. That's why the Lord gave us the Word of Wisdom. He also said that we should retire to our beds early and arise early (see D&C 88:124), that we should not run faster than we have strength (see D&C 10:4), and that we should use moderation in all good things.

"In general, the more food we eat in its natural state—the less it is refined, and the fewer additives it contains—the healthier it will be for us. Food can affect the mind, and deficiencies in certain elements in the body can promote mental depression.

"A good physical examination periodically is a safeguard and may spot problems that can be remedied. Rest and physical exercise are essential, and a walk in the fresh air can refresh the spirit. Wholesome recreation is part of our religion and is a necessary change of pace; even its anticipation can lift the spirit."

—Ezra Taft Benson, "Do Not Despair,” Ensign, Oct. 1986, 2

"Agency, or the power to choose, was ours as spirit children of our Creator before the world was (see Alma 13:3; Moses 4:4). It is a gift from God, nearly as precious as life itself.

"Often, however, agency is misunderstood. While we are free to choose, once we have made those choices, we are tied to the consequences of those choices.

"We are free to take drugs or not. But once we choose to use a habit-forming drug, we are bound to the consequences of that choice. Addiction surrenders later freedom to choose. Through chemical means, one can literally become disconnected from his or her own will."

—Russell M. Nelson, "Addiction or Freedom,” Ensign, Nov. 1988, 7

"A two-year mission today requires good physical health. It requires that you keep your body clean. In your early teenage years, when temptations come to you to take things into your body which are unsuitable, have the courage to resist. Live the Word of Wisdom—no smoking, no drinking of any alcoholic beverages, and no drugs. Keep your body pure—a pure vessel for the Lord."

—Ezra Taft Benson, "Preparing Yourselves for Missionary Service,” Ensign, May 1985, 36
