Here is a prayer to the Holy Spirit before receiving the Sacrament of Reconciliation or Penance. Let us ask God to give us the strength to always make a good confession.
Come, Holy Spirit, into my soul. Enlighten my mind that I may know the sins I ought to confess, and grant me the grace to confess them fully, humbly, and with a contrite heart. Help me to firmly resolve not to commit them again.
O Blessed Virgin, Mother of my Redeemer, mirror of innocence and sanctity and refuge of penitent sinners, intercede for me that I may obtain the grace to make a good confession.
All you blessed Angels and Saints of God, pray for me, a sinner, that I may repent from my sinful ways and that I may be forever united with you. Amen.
