“‘Firmness of mind’ is to be constant and undeterred in one’s progress toward that life which is like God’s; it is to have undimmed vision of the plans and purposes of the Almighty; to enjoy peace and confidence in the Master as the tempests rage on all sides. To look to God with firmness of mind is to be, as Nephi said, steadfast in Christ (see 2 Nephi 31:19–20) to pursue an undeviating course” (McConkie and Millet, Doctrinal Commentary, 2:24).
