The biblical doctrine about the human heart is very rich:
it is mentioned more than 1100 times. In Scripture the heart refers to the interior of a person; we read about the heart of God, but mostly about the human heart. In Jeremiah 31:31-34; 32:37-41 and in Ezechiel 11::17-20; 36:24-27 God promises a new covenant which will be characterized by a new heart and a new spirit:
I shall give you a new heart, and put a new spirit in you; I shall remove the heart of stone from your bodies and give you a heart of flesh instead. I shall put my spirit in you...
(Ez 36: 26-27).
In the letter to the Hebrews chapter 8 Christ is described as the mediator of the new covenant and Jeremiah 31:31-34 is applied to him. He is the one who writes the law of God on our hearts.
How does he do that? Well, the heart of Jesus is the source of living water, that is, of the Spirit, (John 7:37-39).
On Calvary his heart was pierced and blood and water flowed from it. The source of living water was opened, and, as became apparent on the day of Pentecost, the Spirit was poured out on us to renew the face of the earth. The paschal mystery is a pentecostal mystery. The love of God has been poured out in our hearts by the Holy Spirit which has been given us (Rom 5:5).
Since the Heart of Jesus is the source of salvation for the world, together with our founder we see it as our mission to make this known to all:
"May the Sacred Heart of Jesus be loved everywhere."
