Water From Rocks
The desert is a hot place, the worst place to be without water. In Israel, to be without water very long is to die. To be parched in a hot arid place and receive water may have the same impact that Jesus had on the Samaritan woman at the well (another text that I will at least think about in the course of sermon preparation). The human body needs water as much as Christians need Jesus. These are both deep personal needs. To have these needs met usually requires God's community.
