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.
