This verse refers instead to knowledge of what a person has done with his mortal life, how he has lived in relation to the commandments of God. Each person’s knowledge of his life—good or bad—will be perfect at the thine he is raised from the dead. Facades or cover-ups or denials will be no more: we will see as we are seen, know as we are known, and acknowledge before the tribunal of Deity that his ways are just. (See Alma 36:12-14.)
For those who have wasted the days of their probation, this time of judgment will be a moment of singular encounter and confrontation: for those who have been wise in the use of their time and talents, this occasion will be a moment of sublime joy and accomplishment. In short, this is the occasion wherein one’s book of life is opened and the story is read.
