The best thing you can do in the Year of Mercy? by Robert Barron

Sacrament of Reconciliation: The Prayer of Sorrow

My God,
I am sorry for my sins with all my heart,
in choosing to do wrong
and failing to do good.
I have sinned against you
whom I should love above all things.
I firmly intend, with your help,
to do penance,
to sin no more,
and to avoid whatever leads me to sin.
Our Savior Jesus Christ
suffered and died for us.
In his name, my God, have mercy.
Amen.
