“Blessed are all they that mourn.”

3 Nephi 12:4

4 And again, blessed are all they that mourn, for they shall be comforted.

President Harold B. Lee said concerning mourning for our sins:

“To mourn, as the Master’s lesson here would teach, one must show that ‘godly sorrow that worketh repentance’ and wins for the penitent a forgiveness of sins and forbids a return to the deeds of which he mourns. [See 2 Corinthians 7:10.]”
