Confession is a sacrament instituted by Jesus to offer forgiveness of sins committed against God and to reconcile sinners with the Church. It involves four steps: contrition for one's sins, confessing sins to a priest, receiving absolution from the priest, and performing a penance to make amends. Confession allows forgiveness of sins through Christ and repairs one's relationship with God and the Church. It is a liberating experience that helps one lead a life following God's guidance.
