John 6:51

John 6:51. 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 which God puts into us is not natural, so as to be fed upon natural food, like bread and meat; but it is spiritual, and it must live upon spiritual food. That food is nothing less than Christ Jesus himself.
