Here are brief and powerful words of wisdom from Pres. Boyd K. Packer about not needlessly suffering through chronic pain of sin:
“Guilt is spiritual pain. Do not suffer from chronic pain. Get rid of it. Be done with it. Repent and, if necessary, repent again and again and again and again until you—not the enemy—are in charge of you.” (Packer, How to survive in enemy territory, Ensign, October 2012).
