The miracle of water from the rock is God’s response to the people’s rebellion in the wilderness. Moses’ authority is under direct attack. Nonetheless, just as God delivered the people from the bondage of Egypt through the leadership of Moses, so now, again through the actions of Moses, God provides for their needs. Moses is instructed to employ the staff he used to perform the signs and wonders that surrounded the liberation from Egypt. When he strikes the rock, life-giving water flows forth. This is but another example of God’s boundless and compassionate love for sinners.
The justification of the Romans is based on the righteousness that originates in God, a righteousness that gives and sustains life, security, and well-being. According to Paul, we have no right to this relationship with God. It has been given to us, won for us by the Lord Jesus Christ. We did not deserve it. We were sinners, alienated from God, when Christ died for us and gained access for us to the grace that places us in right relationship with God. The prodigious quantity of God’s graciousness is beyond our comprehension. It is poured out like water, life-giving, enriching, and overflowing.
The living water metaphor about which Jesus and the Samaritan woman con verse has a long and rich history in the religious tradition of Israel, where it is seen as a principle of spiritual life. Jesus’ unexplained knowledge of the woman’s marital situation prompts her to call him a prophet and to launch into another discussion about the proper place to worship God. Here too Jesus moves the conversation away from what is merely perceptible to the level of deep spiritual meaning, from a discussion of the place of worship to one that characterizes the manner of worship. The word of salvation comes to the Samaritan village through a woman, it takes root in the hearts of these despised and marginalized people, and it grows into a great harvest.
