Charles Spurgeon Commentary John 6:51

"I am the living bread which came down out of heaven: if any man eat of this bread, he shall live for ever: yea and the bread which I will give is my flesh, for the life of the world." — John 6:51 (ASV)

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.

Christ – God incarnate – is the nourishment of faith, the spiritual food of the everlasting life. The new life that God puts into us is not natural, so it is not fed with natural food, like bread and meat; but it is spiritual, and it must live on spiritual food.

That food is nothing less than Christ Jesus himself.
