But as we know the thirst of Jesus was beyond the physical thirst, it was a thirst for communion with us, a thirst born out of love for us, a love that we cannot even comprehend, a thirst for a well being and for our salvation, a thirst for union with us, a thirst to satisfy the yearning and thirsts of our restless heart, knowing very well like St. Augustine well expressed it once, "You have made us for yourself, Oh Lord, and our heart is restless until it rests in you." Jesus had a deep thirst for you and for me, a thirst for our happiness, a thirst to save us from our self-centeredness, a thirst to save us from our ignorance and lead us into the way of truth, a thirst for justice, a thirst to restore justice and peace,"Blessed are those who hunger and thirst for justice, for they will be satisfied," a thirst to satiate our deepest thirst, as he answered the Samaritan woman, "Jesus answered her, “If you knew the gift of God and who it is that asks you for a drink, you would have asked him and he would have given you living water,” and later on Jesus continues"whoever drinks the water I give them will never thirst. Indeed, the water I give them will become in them a spring of water welling up to eternal life.” But what is this water that Jesus speaks about? In John 7, Jesus says, "Whoever believes in me, as Scripture has said, rivers of living water will flow from within them.”[c] 39 By this he meant the Spirit, whom those who believed in him were later to receive. Up to that time the Spirit had not been given, since Jesus had not yet been glorified." Jesus thirst to share His Holy Spirit with us, the Spirit is the superabundant grace of God, like flowing rivers that no heart could ever exhaust, this is the living gift of God to all those who believe and welcome Him.
And because Jesus thirsts to share His very self with us, he can also be said to be thirsting for our love as Mother Teresa would often say. There is Jesus in the tabernacle, waiting for us so to speak, thirsting to be corresponded in a finite way to His infinite love, and for that reason Jesus would exclaim in his fourth apparition to Saint Margaret Mary, "Behold the Heart which has so loved men that it has spared nothing, even to exhausting and consuming Itself, in order to testify Its love; and in return, I receive from the greater part only ingratitude, by their irreverence and sacrilege, and by the coldness and contempt they have for Me in this Sacrament of Love. But what I feel most keenly is that it is hearts which are consecrated to Me, that treat Me thus." Jesus thirsts for your love and mine.
And yet there is at least another thirst in the heart of Jesus that is the "raison the etre" of the other thirsts, for is an existential thirst, a thirst for life, a thirst for love, a THIRST FOR THE FATHER, in His humanity Jesus had a thirst to worship the Father in all things, Jesus had a thirst to obey the Father and to love His will, His deeper thirst was to glorify the Father and love Him with His whole being, Psalm 42 expresses this experience " As the deer yearns for streams of water, so my soul yearns for you, O God. My soul thirsts for God, for the living God. When can I go and meet with God?"
