President Brigham Young (1801–77) spoke of the extent of the Savior’s efforts to save mankind: “This is the plan of salvation. Jesus will never cease his work until all are brought up to the enjoyment of a kingdom in the mansions of his Father, where there are many kingdoms and many glories, to suit the works and faithfulness of all men that have lived on the earth. Some will obey the celestial law and receive of its glory, some will abide the terrestrial and some the telestial” (Discourses of Brigham Young, sel. John A. Widtsoe [1954], 56).
