Confess your faults one to another, and pray one for another, that ye may be healed. The effectual fervent prayer of a righteous man availeth much. James 5:16.
(WGD 215.1)
If you have given offense to your friend or neighbor, you are to acknowledge your wrong, and it is his duty freely to forgive you. Then you are to seek the forgiveness of God, because the brother whom you wounded is the property of God, and in injuring him you sinned against his Creator and Redeemer. The case is not brought before the priest at all, but before the only true mediator, our great High Priest, who “was in all points tempted like as we are, yet without sin,” and who is “touched with the feeling of our infirmities,” and is able to cleanse from every stain of iniquity....
(WGD 215.2)
True confession is always of a specific character, and acknowledges particular sins. They may be of such a nature as only to be brought before God; they may be wrongs that should be confessed before individuals who have suffered injury through them; or they may be of a general kind that should be made known in the congregation of the people. But all confession should be definite, and to the point, acknowledging the very sins of which you are guilty....
(WGD 215.3)
Confession will not be acceptable to God without sincere repentance and reformation. There must be decided changes in the life; everything offensive to God must be put away. This will be the result of genuine sorrow for sin.—Testimonies for the Church 5:639, 640.
