The Sacrament of Confession (aka Reconciliation or Penance) is a source of a new life for the Christian. It sets the soul ablaze in the love of God. It radically re-orients your life anew.

Change is difficult; admitting that one is a sinner is the grace of God in action. It is only by God’s grace do we have the fortitude and courage to face our ugly self. Who wants to admit one is a sinner? Not many people. But when you realize that holiness is recognized in knowing who you are, that you are a loved sinner, and accepting the invitation to speak with Jesus Christ through the ministry of the priesthood, all is different.
The confession of sins helps us to confront our pride and our wrong-doing in a concrete, loving manner. This sacrament is nothing more, nothing less than taking the merciful hand of God.
Throw yourself onto the mercy of the Triune God. A little encouragement is here in this short video on Confession.
