Purify Our Hearts

O God,
you purify human hearts from sin
and make them whiter than snow.
Pour on us the abundance of your mercy.
Renew the Holy Spirit in us
that we may declare your praise,
be strengthened by your grace,
and obtain rest in the eternal mansions
of the heavenly Jerusalem;
through Jesus Christ our Lord.
Amen.
