This is that bread ... - This is the true bread that came down. The word "that" should not be in the translation.

Shall live for ever - Not on the earth, but in the enjoyments of a better world.

This is that bread which came down from heaven,.... That true bread, the bread of God, the bread of life, living bread; meaning himself, as in John 6:32;

not as your fathers did eat manna, and are dead: this is bread of a quite different nature from that; that was only typical bread, this true; that was the bread of angels, but this is the bread of God; that came but from the air, this from the third heaven; that men ate of, and died; but whoever eats of this, lives for ever; see John 6:49; as follows:

he that eateth of this bread shall live for ever; See Gill on John 6:51.

This is that bread which came down from heaven: not as your fathers did eat manna, and are dead: he that eateth of this bread shall live for ever.

6:58 This is that bread. Himself. He probably laid his hand upon himself as he spoke.

6:58 This is - That is, I am the bread - Which is not like the manna your fathers ate, who died notwithstanding.

58. This is that bread, &c.-a sort of summing up of the whole discourse, on which let this one further remark suffice-that as our Lord, instead of softening down His figurative sublimities, or even putting them in naked phraseology, leaves the great truths of His Person and Office, and our participation of Him and it, enshrined for all time in those glorious forms of speech, so when we attempt to strip the truth of these figures, figures though they be, it goes away from us, like water when the vessel is broken, and our wisdom lies in raising our own spirit, and attuning our own ear, to our Lord's chosen modes of expression. (It should be added that although this discourse has nothing to do with the Sacrament of the Supper, the Sacrament has everything to do with it, as the visible embodiment of these figures, and, to the believing partaker, a real, yea, and the most lively and affecting participation of His flesh and blood, and nourishment thereby of the spiritual and eternal life, here below).

6:52-59 The flesh and blood of the Son of man, denote the Redeemer in the nature of man; Christ and him crucified, and the redemption wrought out by him, with all the precious benefits of redemption; pardon of sin, acceptance with God, the way to the throne of grace, the promises of the covenant, and eternal life. These are called the flesh and blood of Christ, because they are purchased by the breaking his body, and the shedding of his blood. Also, because they are meat and drink to our souls. Eating this flesh and drinking this blood mean believing in Christ. We partake of Christ and his benefits by faith. The soul that rightly knows its state and wants, finds whatever can calm the conscience, and promote true holiness, in the redeemer, God manifest in the flesh. Meditating upon the cross of Christ gives life to our repentance, love, and gratitude. We live by him, as our bodies live by our food. We live by him, as the members by the head, the branches by the root: because he lives we shall live also.
