The most plaintive, agonizing words ever spoken in all of human history were uttered by Jesus Christ as He hung dying on the cross to bring salvation to a condemned world. Part of these words, the seven last words spoken by Jesus from the cross, is given little fanfare in the gospels. All we are told in John 19:28 is:"Jesus is God, therefore His love, His Thirst, is infinite. He the creator of the universe,asked for the love of His creatures.He thirst for our love… These words:‘I Thirst’ –Do they echo in our souls?”Mother Teresa
Afterwards, Jesus knowing that all things were now accomplished, that the scripture might be fulfilled, said: I thirst.But what does this really mean? Was Jesus just complaining that he needed something to drink? He had been beaten to such a point that he was barely recognizable as a human being. The blood was almost completely drained out of his body. He had not had any food or water for many hours and was in an extreme condition of dehydration. Is that was he was talking about? With all of the many other things he had suffered - mockings and insults, skin ripped from his body, bones pulled out of joint, hair pulled from his head and beard, a severe whipping which brought him to the point of death, nails driven into his hands and feet, struggling for each breath as he hung on the cross - why would his one complaint, if that is what it was, be about thirst?
Our Lord was talking about something much deeper than physical thirst. He was talking about a thirst that had driven him his entire life. He was talking about a thirst he felt even before becoming incarnate, when he shared glory with the Father in heaven (John 17:5). He was talking of his great love for humanity, for the people who were responsible for all of the suffering he was experiencing. His thirst is for you and me, for every single human being who has ever lived. Our Lord thirsts for the worst sinner as well as the greatest saint. No one is excluded.
I desire that you know more profoundly the love that burns in My Heart for souls, and you will understand this when you meditate upon My Passion. Call upon My mercy on behalf of sinners; I desire their salvation. (paragraph 186)
My daughter, look into the abyss of My mercy and give praise and glory to this mercy of Mine. Do it in this way: Gather all sinners from the entire world and immerse them in the abyss of My mercy. I want to give Myself to souls; I yearn for souls, My daughter. On the day of My feast, the Feast of Mercy, you will go through the whole world and bring fainting souls to the spring of My mercy. I shall heal and strengthen them. (paragraph 206)
