President Boyd K. Packer admonished those who seek peace of conscience through repentance to persevere until they obtain forgiveness:
“The gospel teaches us that relief from torment and guilt can be earned through repentance. Save for those few who defect to perdition after having known a fulness, there is no habit, no addiction, no rebellion, no transgression, no offense exempted from the promise of complete forgiveness. . . .
“That great morning of forgiveness may not come at once. Do not give up if at first you fail. Often the most difficult part of repentance is to forgive yourself. Discouragement is part of that test. Do not give up. That brilliant morning will come.
“Then ‘the peace of God, which passeth... understanding’ comes into your life once again. [Philippians 4:7]. Then you, like Him, will remember your sins no more. How will you know? You will know! [see Mosiah 4:1–3]” (in Conference Report, Oct. 1995, 22, 24; or Ensign, Nov. 1995, 19–20).
