Prayer for the Twelfth Sunday after Pentecost

O merciful God,
you justified the tax collector
who stood at a distance,
and while beating his breast,
confessed his sins to you.
As we acknowledge our unworthiness,
and ask for your mercy,
forgive all our sins;
through your mercy,
and for the sake of Jesus Christ,
your Son, our Savior.
Amen.
