True faith is focused in and on the Lord Jesus Christ and always leads to righteous actions. The Prophet Joseph Smith taught that “faith is the first principle in revealed religion, and the foundation of all righteousness” and that it is also “the principle of action in all intelligent beings”. Action alone is not faith in the Savior, but acting in accordance with correct principles is a central component of faith. Thus, “faith without works is dead” (James 2:20).
