O blessed Spirit of Truth,
you search the heart and test the inmost thoughts,
help me remember my sins,
and let me see them in your light.
Strengthen me also with courage to confess them truly,
hiding nothing, excusing nothing, keeping back nothing in my heart.
In your mercy, pardon and absolve,
and thus heal me,
that I may arise and sin no more,
through the merits and for the sake
of Jesus Christ, my Lord and only Savior. Amen.
