despair from sin prayer (saint claude de la colombiere)

Prayer:
Lord, I am in this world to show Your mercy to others.
Other people will glorify You by making visible the power of Your grace
by their fidelity and constancy to You.
For my part I will glorify You
by making known how good You are to sinners,
that Your mercy is boundless
and that no sinner no matter how great his offences -
should have reason to despair of pardon.
If I have grievously offended You, My Redeemer,
let me not offend You even more by thinking -
that You are not kind enough to pardon Me. Amen.
-Saint Claude de la Colombiere
