After this, Jesus, knowing that all was now finished, said (to fulfill the Scripture), "I thirst." A jar full of sour wine stood there, so they put a sponge full of the sour wine on a hyssop branch and held it to his mouth.
I thirst. When are we truly thirsty? The Scripture being fulfilled is Psalm 69 which begins, Save me Oh Lord, for the waters have come up to my neck. Save me, Oh Lord. Even Jesus thirsts. Even Jesus is desperate for the water of life.
One time, many years ago, before I was experienced in the outdoors, I went hiking with my brother and sister in law in Big Bend. We hiked in the desert plains below the Chisos mountains. We had stored some water ahead on the trail before we began but the day was hotter than we expected and we ran out. We only came across shade once or twice a mile. My sister-in-law started to faint and so my brother stayed with her in the last shade spot we could find. I left my pack, since it was too heavy, and went ahead looking for the water, hoping it was still there.
It was hot.
I was truly thirsty. My body ached. I was falling forward more than walking. It was about a mile and half with the sun crisping me over(I had stopped sweating for, at least, an hour). About halfway through, I started hearing voices. I was hallucinating. I turned around, once, after a voice and tripped and fell. I laid their for minutes before rising to walk again. I thirsted.
Jesus was tired. Crucifixion kills through many ways. You can die on a cross from heart failure, hypovolemic shock, acidosis, arrythmia, sepsis, dehydration, or, most commonly, asphyxiation. Exhaustion leading to oxygen deficiency leading to heavy breathing. He was on the cross for three hours and this fifth word is near the end. 'I thirst'. There is nothing modest here. We see the desperation of God, the willingness of God to go even further for us. Jesus does not ignore his body. He thirst. Darkness has fallen across the land. Our Lord and Savior has been in agony for hours, and he thirsts, and what do they give him but sour wine.
And he drinks. Because he is tired. Eternal life is not simply living forever. Jesus thirsts. The pain is real. The exhaustion is real. He has nothing left yet he still cries out, he still drinks, he still has two more words to say.
