Charles Ellicott Commentary John 6:35

"Jesus said unto them. I am the bread of life: he that cometh to me shall not hunger, and he that believeth on me shall never thirst." — John 6:35 (ASV)

I am the bread of life.—Compare again the conversation with the woman of Samaria. Here they have asked for “this bread,” the bread which gives life, as distinct from that which perishes. It is now present with them. He is that bread, whose characteristic is life. He is the Word of God, revealing God to man, teaching the eternal truths which are the life of the spirit just as bread is of the body.

He that cometh to me . . . he that believeth on me.—The natural bread satisfied no need unless it was appropriated and eaten. Prompted by hunger, they had taken into hand and mouth the loaves He had given them, and were filled. The same law holds for the spiritual bread. It is taken by him who comes to Christ; it is eaten by him who believes on Him, and it satisfies every need. It sustains the spiritual life in strength, and refreshes it in weariness. The bread of life gives a principle of life, and he who hungers and thirsts for it shall also be filled, but with that which abides, so that he shall never hunger and shall never thirst. (Compare to Matthew 5:6.)
