President Boyd K. Packer, President of the Quorum of the Twelve Apostles, testified that we can apply the Atonement of Jesus Christ to remove our guilt:
“For some reason we think the Atonement of Christ applies only at the end of mortal life to redemption from the Fall, from spiritual death. It is much more than that. It is an ever-present power to call upon in everyday life. When we are racked or harrowed up or tormented by guilt or burdened with grief, He can heal us. While we do not fully understand how the Atonement of Christ was made, we can experience ‘the peace of God, which passeth all understanding’ [Philippians 4:7]. …
“We all make mistakes. Sometimes we harm ourselves and seriously injure others in ways that we alone cannot repair. We break things that we alone cannot fix. It is then in our nature to feel guilt and humiliation and suffering, which we alone cannot cure. That is when the healing power of the Atonement will help.
“The Lord said, ‘Behold, I, God, have suffered these things for all, that they might not suffer if they would repent’ [D&C 19:16]. …
“The Atonement has practical, personal, everyday value; apply it in your life. It can be activated with so simple a beginning as prayer. You will not thereafter be free from trouble and mistakes but can erase the guilt through repentance and be at peace” (in Conference Report, Apr. 2001, 28–29; or Ensign, May 2001, 23–24).
