The right of everyone to drink from a water fountain regardless of color became a battle line in the Jim Crow South at the peak of the civil rights movement. It was a central point of humanity that everyone had the same need for water and to deny it was to deny human dignity.
I am tempted to go into the Chase branch in the University District just to ask for a glass of water and to apply for a job. Or maybe hand out free water on hot days downtown. Or maybe help someone, somewhere in the world that is underdeveloped, find a way to get clean drinking water.
When Christ said from the Cross "I Thirst" he was making a final statement of his identity with use, as a person of God completely God and completely human. Everyday in a world with growing shortages of water someone says "I thirst" and Jesus says it with them.
