An Act of Consecration to the Sacred Heart of Jesus

 O Sacred Heart of Jesus, tender and compassionate,

I come before you to consecrate my life to your loving care. You are the source of all goodness and mercy, the fountain of love that overflows for humanity.

In humble surrender, I offer you my entire being, my thoughts, words, and actions, my joys and sorrows, my hopes and fears, my past, present, and future. I place everything in your Sacred Heart, trusting in your divine providence.

I seek refuge in your boundless love and mercy. Please accept me as your devoted servant, that I may follow you faithfully and imitate your virtues. I desire to live each moment in intimate communion with you, to be a witness of your love in the world.

Sacred Heart of Jesus, I consecrate my heart to you, asking that you purify it, heal its wounds, and inflame it with your love. Make my heart like unto yours, gentle and humble, overflowing with compassion and forgiveness.

I consecrate my mind to you, Sacred Heart of Jesus, that my thoughts may be guided by truth, wisdom, and purity. Help me to discern your will and to seek your guidance in all things. May my intellect be dedicated to the pursuit of knowledge and understanding, and may it be a source of light and hope for others.

I consecrate my hands to you, Sacred Heart of Jesus, that I may use them to do works of mercy and compassion. Help me to serve others selflessly, to reach out to the needy, and to bring comfort to the suffering and the oppressed. May my actions be a reflection of your love and a testament to your presence.

I consecrate my whole being to you, Sacred Heart of Jesus, knowing that you will transform and sanctify me. Take complete control of my life, guide my steps, and lead me ever closer to the Father. I surrender myself to your divine will, trusting in your providence.

Sacred Heart of Jesus, I place my trust in you. With confidence and love, I consecrate myself to you, seeking to live in intimate union with you. May your Sacred Heart be my refuge, my strength, and my joy, both now and for all eternity.

I make this act of consecration in the name of the Father, and of the Son, and of the Holy Spirit. Amen.

Sacred Heart of Jesus, have mercy on us.
