The Word of Wisdom was being discussed by me and a few others in the chat sometime earlier, I and I assume some others, were a little confused about it's details. I think I've found something which helps to sum it up. The revelation given to the Prophet Joseph Smith uses the following words to define and advise against the use of harmful substances and beverages: "Strong drinks (meaning alcoholic or other harmful beverages) are not for the belly." (Doctrine and Covenants 89:7) "Tobacco is not for the body...and is not good for man." (Doctrine and Covenants 89:8) "Hot drinks [meaning black tea and coffee] are not for the body." (Doctrine and Covenants 89:9) The Word of Wisdom not only admonishes against the use of harmful substances, but it also describes those foods which are good for man: "All wholesome herbs God hath ordained for the constitution, nature, and use of man— "Every herb in the season thereof, and every fruit in the season thereof; "Flesh … of beasts and of the fowls of the air...are to be used sparingly; "All grain is ordained for the use of man...to be the staff of life... "All grain is good for the food of man; as also the fruit of the vine." (Doctrine and Covenants 89:10–12, 14, 16) The Word of Wisdom is a law and a principle with promise. When men and women obey the provisions of the law, they receive the blessings associated with those provisions. However, if they do not obey, there will be both temporal and spiritual consequences.
