I DESIRE NEVER TO GRIEVE THEE BY UNFAITHFULNESS TO GRACE

An Act of Oblation to the Holy Spirit

On my knees before the great cloud of heavenly witnesses, I offer myself body and soul to Thee, eternal Spirit of God. I adore the brightness of Thy purity, the unerring keenness of Thy justice and the might of Thy love. Thou art the strength and light of my soul. In Thee I live and move and have my being. I desire never to grieve Thee by unfaithfulness to grace, and I pray with all my heart to be kept from the smallest sin against Thee.

Make me faithful in every thought, and grant that i may always listen to Thy voice, watch for Thy light, and follow Thy gracious inspirations. I cling to Thee and give myself to Thee, and I ask Thee by Thy compassion to watch over me in my weakness. Holding the pierced feet of Jesus, looking at His five Wounds, trusting in His Precious Blood and adoring His opened side and stricken Heart, I implore Thee, adorable Spirit, Helper of my infirmity, so to keep me in Thy grace that I may never sin agasint Thee with the sin which Thou wilt not forgive.

Grant to me the grace, O Holy Spirit, Spirit of the Father and of the Son, to say to Thee always and everywhere, "Speak, Lord, for Thy servant hears."  Amen.

I found this very pure, pious offering in Fr Paul O'Sullivan's book, The Holy Ghost - Our Greatest Friend.
