St. Augustine’s short, simple prayer that leads to holiness

Let us hunger and thirst for holiness, and we shall be satisfied ...

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.
