Water Bread And Light In John's Gospel

Water, Bread and Light are three important symbols in John’s Gospel. How do these symbols help the Johannine community to understand the identity of Jesus?
The Gospel of John addresses the Johnannine audience’s journey of faith with theological reflections on the origin and identity of the “Word”. The author uses universal symbols of the light, the bread and the water to represent the identity of Jesus to the Johnannine community, thus reinforcing a high Christology.

As he proclaims, “I am the living bread” (6:25). These ego emi statements reveal significant information about the identity of Jesus by symbolically referring to the gift of God which “makes those who believe see natural hunger, thirst and death as insignificant” (R. Brown). Consumption of the “bread of life” promises those who believe that they shall achieve eternal life and become children of God who will share the close bond between God, the Father and
