What is the act that say we are sorry for our sins?

The act of expressing sorrow for one's sins is often referred to as "confession" or "repentance." In many religious traditions, this involves acknowledging wrongdoing, feeling genuine remorse, and seeking forgiveness from God or a higher power. In Christianity, this is often encapsulated in the Sacrament of Reconciliation, where believers confess their sins to a priest. The act signifies a desire for spiritual renewal and a commitment to change.
