Praise Be the Sacred Heart of Jesus

Saint Faustina wrote in her diary in June 1937:

June 4. Today is the Feast of the Most Sacred Heart of Jesus. During Holy Mass, I was given the knowledge of the Heart of Jesus and of the nature of the fire of love with which He burns for us and of how He is an Ocean of Mercy. Then I heard a voice: Apostle of My mercy, proclaim to the whole world My unfathomable mercy. Do not be discouraged by the difficulties you encounter in proclaiming My mercy. These difficulties that affect you so painfully are needed for your sanctification and as evidence that this work is Mine. My daughter, be diligent in writing down every sentence I tell you concerning My mercy, because this is meant for a great number of souls who will profit from it. (Diary entry 1142)

Prayer to the Most Holy and Sacred Heart of Jesus

O most holy heart of Jesus, fountain of every blessing, I adore you, I love you, and with lively sorrow for my sins I offer you this poor heart of mine. Make me humble, patient, pure and wholly obedient to your will. Grant, Good Jesus, that I may live in you and for you. Protect me in the midst of danger. Comfort me in my afflictions. Give me health of body, assistance in my temporal needs, Your blessing on all that I do, and the grace of a holy death. Amen.
