O blessed Spirit of Truth, Thou who searchest the heart and triest the inmost thoughts, bring, I pray Thee, my sins to my remembrance, and grant me light to see and find them out. Strengthen me also with courage to confess them truly, hiding nothing, excusing nothing, keeping back nothing in my heart; that I may, of Thy mercy, obtain pardon and entire absolution; and, thus healed, may arise and sin no more, through the merits and for the sake of Jesus Christ, my Lord and only Saviour. Amen.
