“According to Oliver B. Huntington the Prophet Joseph Smith said that ‘a man can do as much in this life in one year as he can do in ten years in the spirit world without the body.’ If … a person has enjoyed the privileges of gospel understanding but chooses in this life to deny or defy that light, to reject the truth and avoid the works of righteousness when he knows better, it becomes extremely difficult for him to turn around, to change directions at the time of death” (McConkie and Millet, Doctrinal Commentary, 3:256).
