A Psalm of David. A Contemplation. Blessed is he whose transgression is forgiven, Whose sin is covered. Blessed is the man to whom the LORD does not impute iniquity, And in whose spirit there is no deceit.
When I kept silent, my bones grew old Through my groaning all the day long. For day and night Your hand was heavy upon me; My vitality was turned into the drought of summer. Selah
I acknowledged my sin to You, And my iniquity I have not hidden. I said, "I will confess my transgressions to the LORD," And You forgave the iniquity of my sin. Selah

Another example where confession is an important element in worship. A major part is the relationship between parent and child, a relationship of transparency. My earthly father was not overly sympathetic about bandaging a cut caused by my loss of control and intemperate behavior. Cut would get fixed, but I would also get a teaching about not being open with a parent.

Worship must include confession and repentance.
