There is no sin or transgression, pain or sorrow, which is outside of the healing power of His Atonement.
Through His Atonement, He heals not only the transgressor, but He also heals the innocent who suffer because of those transgressions. As the innocent exercise faith in the Savior and in His Atonement and forgive the transgressor, they too can be healed.
When we sin, Satan tells us we are lost. In contrast, our Redeemer offers redemption to all—no matter what we have done wrong—even to you and to me.
As you consider your own life, are there things that you need to change? Have you made mistakes that still need to be corrected? If you are suffering from feelings of guilt or remorse, bitterness or anger, or loss of faith, I invite you to seek relief. Repent and forsake your sins. Then, in prayer, ask God for forgiveness. Seek forgiveness from those you have wronged. Forgive those who have wronged you. Forgive yourself.
The plan of salvation could not be brought about without an atonement… The atoning sacrifice had to be carried out by the sinless Son of God, for fallen man could not atone for his own sins. The Atonement had to be infinite and eternal to cover all men throughout all eternity. Through His suffering and death, the Savior atoned for the sins of all men. His Atonement began in Gethsemane and continued on the cross and culminated with the Resurrection.
Ask God for forgiveness. Seek forgiveness from those you have wronged. Forgive those who have wronged you. Forgive yourself.
When we repent, the Lord allows us to put the mistakes of the past behind us.
