“We must confess all our sins to the Lord. In addition, we must confess serious sins—such as adultery, fornication, homosexual relations, spouse or child abuse, and the sale or use of illegal drugs—which might affect our standing in the Church, to the proper priesthood authority. If we have sinned against another person, we should confess to the person we have injured. Some less serious sins involve no one but ourselves and the Lord. These may be confessed privately to the Lord” (Gospel Principles [2009], 111).
“Jesus Christ has prescribed a very clear method for us to repent and find healing in our lives. The cure for most mistakes can be found by seeking forgiveness through personal prayer. However, there are certain spiritual illnesses, particularly those dealing with violations of the moral law, which absolutely require the assistance and treatment of a qualified spiritual physician. …
“If you ‘awake to a sense of your awful situation’ [Ether 8:24] and wish to return to full spiritual health, see your bishop. He holds the keys and can help you along the pathway of repentance” (Boyd K. Packer, “The Key to Spiritual Protection,” Ensign or Liahona,Nov. 2013, 28).
Elder Richard G. Scott:
“Spencer W. Kimball [gave] a superb guide to forgiveness through repentance. It has helped many find their way back. He [identified] five essential elements of repentance.
“Sorrow for sin. Study and ponder to determine how serious the Lord defines your transgression to be. That will bring healing sorrow and remorse. It will also bring a sincere desire for change and a willingness to submit to every requirement for forgiveness. …
“Abandonment of sin. This is an unyielding, permanent resolve to not repeat the transgression. By keeping this commitment, the bitter aftertaste of that sin need not be experienced again. …
“Confession of sin. You always need to confess your sins to the Lord. If they are serious transgressions, such as immorality, they need to be confessed to a bishop or stake president. Please understand that confession is not repentance. It is an essential step, but is not of itself adequate. Partial confession by mentioning lesser mistakes will not help you resolve a more serious, undisclosed transgression. Essential to forgiveness is a willingness to fully disclose to the Lord and, where necessary, His priesthood judge all that you have done. …
“Restitution for sin. You must restore as far as possible all that which is stolen, damaged, or defiled. Willing restitution is concrete evidence to the Lord that you are committed to do all you can to repent.
“Obedience to all the commandments. Full obedience brings the complete power of the gospel into your life with strength to focus on the abandonment of specific sins. It includes things you might not initially consider part of repentance, such as attending meetings, paying tithing, giving service, and forgiving others. …
“I would add a sixth step: Recognition of the Savior. Of all the necessary steps to repentance, I testify that the most critically important is for you to have a conviction that forgiveness comes because of the Redeemer. It is essential to know that only on His terms can you be forgiven” (Richard G. Scott, “Finding Forgiveness,” Ensign, May 1995, 76).]
“Church discipline is an inspired process that takes place over a period of time. Through this process and through the Atonement of Jesus Christ, a member can receive forgiveness of sins, regain peace of mind, and gain strength to avoid transgression in the future. Church disciplinary action is not intended to be the end of the process. It is designed to help Heavenly Father’s children continue in their efforts to return to full fellowship and the full blessings of the Church. The desired result is that the person make whatever changes are necessary to repent completely” (“Church Disciplinary Councils,” True to the Faith: A Gospel Reference [2004], 38).
