Holy Spirit, come into my heart; draw it to Thee by Thy power, O my God, and grant me charity with filial fear. Preserve me, O ineffable Love, from every evil thought; warm me, inflame me with Thy dear love, and every pain will seem light to me. My Father, my sweet Lord, help me in all my actions. Jesus, love, Jesus, love. Amen.
