When Jesus came to earth, He was the fulfillment of the Law. There is no condemnation for those who are inChrist. If you’re truly saved, your good behavior is a manifestation of your conversion, thus negating the need for more laws to follow. Obeying the ordinances of man doesn’t bring honor to God.
“Three types of things are prohibited to man by the Word of Wisdom—tobacco, strong drinks, and hot drinks…through the cleanliness resulting from keeping this law of health, and by ‘walking in obedience to the commandment’, the saints will qualify for the companionship of the Holy Spirit…” Mormon Doctrine, pgs. 845-847
