I give myself and consecrate to the Sacred Heart of our Lord Jesus Christ, my person and my life, my actions, pains and sufferings, so that I may be unwilling to make use of any part of my being other than to honor, love and glorify the Sacred Heart. This is my unchanging purpose, namely, to be all His, and to do all things for the love of Him, at the same time renouncing with all my heart whatever is displeasing to Him. I therefore take You, O Sacred heart, to be the only object of my love, the guardian of my life, my assurance of salvation, the remedy of my weakness and inconstancy, the atonement for all the faults of my life and my sure refuge at the hour of death. 

Be then, O Heart of goodness, my justification before God the Father, and turn away from me the strokes of his righteous anger. O Heart of love, I put all my confidence in You, for I fear everything from my own wickedness and frailty, but I hope for all things from Your goodness and bounty.

Remove from me all that can displease You or resist Your holy will; let your pure love imprint Your image so deeply upon my heart, that I shall never be able to forget You or to be separated from You.

May I obtain from all Your loving kindness the grace of having my name written in Your Heart, for in You I desire to place all my happiness and glory, living and dying in bondage to You. 

Amen.

Note: This consecration which was first composed by St. Margaret Mary in honor of the Sacred Heart and called by her "The Little Consecration," possesses the very precious privilege of having been inspired and recommended by our Lord himself to His faithful servant.
