ACT OF CONSECRATION TO THE HOLY SPIRIT
On my knees before the great multitude of heavenly witnesses I offer myself, soul and body, to You, Eternal Spirit of God. I adore the brightness of Your purity, the unerring keenness of Your justice and the might of Your love. You are the Strength and Light of my soul. In You I live and move and am. I desire never to grieve You by unfaithfulness to grace and I pray with all my heart to be kept from the smallest sin against You. Mercifully guard my every thought and grant that I may always watch for Your light and listen to Your voice and follow Your gracious inspirations. I cling to You and give myself to You and ask You by Your compassion to watch over me in my weakness. Holding the pierced Feet of Jesus and looking at His Five Wounds and trusting in His Precious Blood and adoring his opened Side and stricken Heart, I implore You, Adorable Spirit, Helper of my infirmity, so to keep me in Your grace that I may never sin against You. Give me grace, O Holy Ghost, Spirit of the Father and the Son to say to You always and everywhere, "Speak, Lord, for Your servant heareth." Amen.
The beautiful Act of Consecration to the Holy Spirit is from the Novena to the Holy Spirit--nine days of prayer preceding the feast of Pentecost. The complete Novena is here.
