Prayer to the Blessed Virgin

O most holy, most amiable and most glorious Virgin, Mother of God,
Mistress and Advocate to whom we are all vowed and consecrated, making it our glory to belong to thee as children, servants and slaves for time and eternity, behold! with common accord, we throw ourselves at thy feet to renew our vows of fidelity and servitude to thee and to pray thee that as we belong entirely to thee, thou wouldst offer, dedicate, consecrate and immolate to the Sacred Heart of our adorable Jesus, ourselves and all that we are, all that we shall do and suffer, without reserving anything for ourselves. 
We wish to have no other liberty except that of loving Him, no other glory except that of belonging to Him as slaves and victims of His pure love, no other will or power but that of pleasing Him and contenting Him in everything, even at the price of our lives. And since thou hast all power over the amiable Heart of thy Divine Son, grant, O most charitable Mother, that He may receive and accept this consecration which we make today in thy presence, and through thy mediation, with the protestations of our fidelity, relying on His grace and thy help, which we beg thee not to refuse us. 
O, our sweet Hope, make us feel thy power over the amiable Heart of Jesus, and use thy influence on our behalf to lodge us there always. Pray Him to exercise His sovereign empire over our souls, making His love reign in our hearts, in order that He may consume us and transform us entirely into Himself. May He be our Father, our Spouse, our Protection, our Treasure, our Delight, our Love and our All in all things; may He destroy and annihilate in us all that is of ourselves and put in place of it all that is of Himself, in order that we may be able to be pleasing to Him. May He be the support of our powerlessness, the strength of our weakness, the joy of all our sadness. 
O Sacred Hearts of Jesus and Mary, repair all our failings, supply for all that is wanting to us, burn our hearts in your holy ardors; consume all our coldness and cowardice in loving and serving you, since we wish to make all our holiness and happiness consist in living and dying in the state of slaves of the adorable Heart of Jesus, and servants of his holy Mother.
Amen
