What does John 6:58 mean?
Once again, Jesus uses the phrase "this is the bread that came down from heaven" (John 6:50). The emphasis on the word "this" is crucial; it shows that Christ's intention is to explain a symbol, not to introduce some new idea. The Bread of Life is Jesus Christ (John 6:48), and "eating" that bread means accepting Him as the One sent from God the Father (John 6:27–29).Jesus has already made a contrast between the manna Israel was given in the wilderness (Exodus 16) and the "true bread from heaven" which God now provides (John 6:32–33, 51). This, in part, was a response to a challenge from the crowd. Despite having already seen many miracles from Jesus (John 6:2, 9–14), the crowd demanded that Jesus out-do the miraculous provision of manna as proof of His legitimacy (John 6:30–31). Jesus, in turn, has taught that this is what His role as Messiah has already done: given something more than physical food. The Bread of Life provided in Christ leads to eternal life, while the manna in the wilderness only led to temporary, physical life.
