Honor the principle of the Word of Wisdom and you will receive the promised blessings. “All saints,” the revelation promises, “who remember to keep and do these sayings, walking in obedience to the commandments,” are promised that they “shall receive health in their navel and marrow to their bones” and “shall run and not be weary, and shall walk and not faint”   (D&C 89:18, 20).

        The Word of Wisdom does not promise you perfect health, but it teaches how to keep the body you were born with in the best condition and your mind alert to delicate spiritual promptings.....

        The promise of health for living the standard of the revelation is not limited to members of the Church. Tell your nonmember friends about the Word of Wisdom and urge them to live it.

        And then there is a greater blessing promised in the Word of Wisdom. Those who obey it are promised that they “shall find wisdom and great treasures of knowledge, even hidden treasures” (D&C 89:19). This is the personal revelation through which you can detect invisible crocodiles or hidden mines or other dangers....

        There’s a final promise in the revelation. Speaking again of those who keep and do and obey these commandments, the Lord said, “I … give unto them a promise, that the destroying angel shall pass by them, as the children of Israel, and not slay them” (D&C 89:21).  That is a remarkable promise.
