Blessings for Obeying the Word of Wisdom
Doctrine and Covenants 89:18–21
18 And all saints who remember to keep and do these sayings, walking in obedience to the commandments, shall receive health in their navel and marrow to their bones;
19 And shall find wisdom and great treasures of knowledge, even hidden treasures;
20 And shall run and not be weary, and shall walk and not faint.
21 And I, the Lord, give unto them a promise, that the destroying angel shall pass by them, as the children of Israel, and not slay them. Amen.
President Boyd K. Packer said:
“Your body is the instrument of your mind. In your emotions, the spirit and the body come closest to being one. What you learn spiritually depends, to a degree, on how you treat your body. That is why the Word of Wisdom is so important. The habit-forming substances prohibited by that revelation—tea, coffee, liquor, tobacco—interfere with the delicate feelings of spiritual communication, just as other addictive drugs will do. Do not ignore the Word of Wisdom, for that may cost you the ‘great treasures of knowledge, even hidden treasures’ promised to those who keep it. And good health is an added blessing.”
