God, our Heavenly Father, governs His children by law. He has instituted laws for our perfection. If we obey His laws, we receive the blessings pertaining to those laws. If we do not obey, we receive the consequences.

The Word of Wisdom is a law—a principle with promise. If we obey the provisions of the law, we receive the promises. If we do not, there will be both temporal and spiritual consequences. – Ezra Taft Benson, “A Principle with a Promise,” Ensign (CR) May 1983
