President Ezra Taft Benson (1899–1994) taught about the difference between worldly sorrow and the deeper godly sorrow necessary for repentance:
“It is not uncommon to find men and women in the world who feel remorse for the things they do wrong. Sometimes this is because their actions cause them or loved ones great sorrow and misery. Sometimes their sorrow is caused because they are caught and punished for their actions. Such worldly feelings do not constitute ‘godly sorrow.’ …
“Godly sorrow is a gift of the Spirit. It is a deep realization that our actions have offended our Father and our God. It is the sharp and keen awareness that our behavior caused the Savior, He who knew no sin, even the greatest of all, to endure agony and suffering. Our sins caused Him to bleed at every pore. This very real mental and spiritual anguish is what the scriptures refer to as having ‘a broken heart and a contrite spirit.’ (See 3 Ne. 9:20; Moro. 6:2; D&C 20:37; 59:8; Ps. 34:18; 51:17; Isa. 57:15.) Such a spirit is the absolute prerequisite for true repentance” (“A Mighty Change of Heart,” Ensign, Oct. 1989, 4).
Elder Richard G. Scott of the Quorum of the Twelve Apostles further explained one of the reasons for godly sorrow: “The painful consequences of sin were purposely put in His plan of happiness by a compassionate Father in Heaven so that you need not follow that tragic path in life. A sinner will not only suffer in this life, but sins that have not been forgiven through true repentance will cause anguish beyond the veil [see D&C 19:4, 15–24]” (in Conference Report, Oct. 2002, 94; or Ensign, Nov. 2002, 87).
