“Our Leaders Were Mighty Men in the Faith of the Lord”

Joseph F. McConkie, Robert L. Millet
It was not mighty warriors, men mighty in strength, but men mighty in the faith of the Lord that consistently led the Nephites to victory over their blood-drinking enemies, the Lamanites. Faith in God is a weapon more to be feared than the sharpness of a sword or the muscle and sinew that wields it. See also 3 Nephi 3:19.
