No Doubt About It - A Powerful Sacrament

Sacrament - a visible form of grace - of Conversion (CCC-1423); of Penance (CCC-1423); of Confession (CCC-1424); of Forgiveness (CCC-1424); and Reconciliation (CCC 1424). - from That Catholic Show

Every individual nature that has not experienced God in prayer remains cut off from itself. Every human love that omits prayer losses what is finest and most distinctive in the presence of the Beloved. All reconciliation that is brought about without prayer remains extrinsic to those reconciled. -- Maurice Nedoncelle

Though this quote is not part of That Catholic Show video, I feel that they have done a pretty good job of setting the stage for how one should prepare to enter into the Sacrament of Reconciliation. Prayer is truly instrumental.
