The Jews had always regarded the manna in the wilderness as the bread of God (Psalm 78:24, Exodus 16:15). There was a strong Rabbinic belief that when the Messiah came he would give manna from heaven. This was the supreme work of Moses. Now the Jewish leaders were demanding that Jesus produce manna from heaven as proof to his claim to be the Messiah. Jesus responds by telling them that it was not Moses who gave the manna, but God. And the manna given to Moses and the people was not the real bread from heaven, but only a symbol of the bread to come. Jesus makes the claim which only God can make: I am the bread of life. The bread which Jesus offers is none else than the very life of God. This is the true bread which can truly satisfy the hunger in our hearts. The manna from heaven prefigured the superabundance of the unique bread of the Eucharist or Lord’s Supper which Jesus gave to his disciples on the eve of his sacrifice.
The manna in the wilderness sustained the Israelites on their journey to the Promised Land. It could not produce eternal life for the Israelites. There are two fundamental types of hunger – physical and spiritual. Only the Lord Jesus can satisfy the deepest hunger in our heart – the hunger for everlasting truth, life, and love. Jesus alone can satisfy our hunger for truth – because in him alone is the Truth which is found in God.
