I often get questions from others wondering why we have the Word of Wisdom. Why can't you have coffee or tea? Does that mean you can't have caffeinated sodas? If red wine can help the heart, why can't you drink it? I often don't know the complete answer to most of the questions I am asked. I try my hardest to answer them and seek more knowledge from leaders and Heavenly Father. Even though I follow the Word of Wisdom, I have a confession for you. I love the taste of coffee. My favorite ice cream is coffee flavored even. Though, I've never had a cup of coffee, it is still something my taste buds long for. That sparks even more questions from others "if you love it, why don't you drink it?" So, ask yourself this: why do we follow the Word of Wisdom? The answer is actually quite simple. The Lord has asked this of us and he will bless us if we listen.
Thomas S. Monson gave a talk during the General Priesthood Session in October 2016, called "Principles and Promises". He says "In 1833 the Lord revealed to the Prophet Joseph Smith a plan for healthy living. That plan is found in the 89th section of the Doctrine and Covenants and is known as the Word of Wisdom. It gives specific direction regarding the food we eat, and it prohibits the use of substances which are harmful to our bodies." This is when the Lord revealed revelation to Joseph Smith to help the people of the gospel. He goes on to say "Those who are obedient to the Lord’s commandments and who faithfully observe the Word of Wisdom are promised particular blessings, among which are good health and added physical stamina.… May we care for our bodies and our minds by observing the principles set forth in the Word of Wisdom, a divinely provided plan. With all my heart and soul, I testify of the glorious blessings which await us as we do." The Lord will bless us all.
