Here the Lord contrasts those who think it is vanity and foolishness to serve God with those who have “feared the Lord” with their faith and obedience. The names of the righteous are recorded in the Lord’s “book of remembrance,” which is the Lamb’s Book of Life (see Alma 5:57-58; D&C 76:68; D&C 88:2; D&C 132:19).
They become the “jewels” of the Lord (see D&C 101:3) in that they inherit the kingdom of God, which is like a “pearl of great price’ (see Matthew 13:44-46). In the fervent heat of the Second Coming (see D&C 101:25) the counterfeit jewels of the wicked will be melted away as so much dross, and the genuine jewels, who are the righteous, will shine forth with great glory for all the world to see.”
