A prayer from St. Augustine to grow in holiness

Breathe in me, O Holy Spirit,
that my thoughts may all be holy.
Act in me, O Holy Spirit,
that my work, too, may be holy.

Draw my heart, O Holy Spirit,
that I love but what is holy.

Strengthen me, O Holy Spirit,
to defend all that is holy.

Guard me, then, O Holy Spirit,
that I always may be holy. Amen.
