One can live without food for several days, but not without water.
Water is a source of life and growth for all living things.
The image of “Living water” is used throughout the scripture as a symbol of God’s wisdom, a wisdom that imparts life and blessing to all who receive it.
Also a symbol for the Jews of thirst of the soul for God, symbolized the Holy Spirit and his work of recreating us in God’s image and sustaining in us the new life which comes from God.
Many knows God’s word, but the difference is: few “put into action.”
Jesus is the “Living water.”
