President Spencer W. Kimball (1895–1985) explained why one who has sinned feels the burden of guilt and the need for repentance:
“As repentance gets under way, there must be a deep consciousness of guilt, and in that consciousness of guilt may come suffering to the mind, the spirit, and sometimes even to the body. In order to live with themselves, people who transgress must follow one or the other of two alternatives. The one is to sear their conscience or dull their sensitivity with mental tranquilizers so that their transgression may be continued. Those who choose this alternative eventually become calloused and lose their desire to repent. The other alternative is to permit remorse to lead one to total sorrow, then to repentance, and finally on to eventual forgiveness.
“Remember this, that forgiveness can never come without repentance. And repentance can never come until one has bared his soul and admitted his actions without excuses or rationalizations. He must admit to himself that he has sinned, without the slightest minimization of the offense or rationalizing of its seriousness, or without soft-pedaling its gravity. He must admit that his sin is as big as it really is and not call a pound an ounce. Those persons who choose to meet the issue and transform their lives may find repentance the harder road at first, but they will find it the infinitely more desirable path as they taste of its fruits” (“The Gospel of Repentance,” Ensign, Oct. 1982, 4).
