John 6:51 - Clarke's commentary and critical notes on the Bible

I am the living bread which came down from heaven: if any man eat of this bread, he shall live for ever: and the bread that I will give is my flesh, which I will give for the life of the world. Is my flesh, which I will give, etc. - Our Lord explains his meaning more fully, in these words, than he had done before. Having spoken so much of the bread which feeds and nourishes the soul, and preserves from death, the attention of his hearers was fixed upon his words, which to them appeared inexplicable; and they desired to know what their meaning was. He then told them that the bread meant his flesh, (his life), which he was about to give up; to save the life of the world. Here our Lord plainly declares that his death was to be a vicarious sacrifice and atonement for the sin of the world; and that, as no human life could be preserved unless there was bread (proper nourishment) received, so no soul could be saved but by the merit of his death. Reader, remember this: it is one of the weightiest, and one of the truest and most important sayings in the book of God.
