President Boyd K. Packer, President of the Quorum of the Twelve Apostles, taught how the Atonement can heal us of our errors:
"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....
“If Christ had not made His Atonement, the penalties for mistakes would be added one on the other. Life would be hopeless. But He willingly sacrificed in order that we may be redeemed. . . .
“We can even ‘retain a remission of [our] sins’ [Mosiah 4:12]. Baptism by immersion is for the remission of our sins. That covenant can be renewed by partaking of the sacrament each week [see D&C 27:2].
“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,May2001,23–24).
