The metaphor of thirst is used throughout the Gospel of John to characterize the believer’s relationship to the spirit. Whoever comes to me, Jesus says, will never be thirsty, for, “Out of the believer’s heart”, or as the Greek renders it, out of the believer’s belly, “shall flow rivers of living water.”(1) Yet, Jesus himself cries from the cross in his final hour, “I thirst,” suggesting, perhaps, that this side of the grave our deepest longing – our thirst – for wholeness, for union, for belonging, will not be quenched.
A few days ago I was watching drops form on the inside of a window. Moisture condenses on the cold glass and forms drops, given shape by the ratio of surface tension to gravity. At a certain point the drop drops and runs down the surface at a speed determined by gravity and the contact between the drop and the glass. There are some remarkable physical laws at work in condensation, the formation of drops and the timing and qualities of their dropping.
