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. 52 The Jews therefore strove one with another, saying, How can this man give us his flesh to eat? 53 Jesus therefore said unto them, Verily, verily, I say unto you, Except ye eat the flesh of the Son of man and drink his blood, ye have not life in yourselves. 54 He that eateth my flesh and drinketh my blood hath eternal life: and I will raise him up at the last day. 55 For my flesh is meat indeed, and my blood is drink indeed. 56 He that eateth my flesh and drinketh my blood abideth in me, and I in him. 57 As the living Father sent me, and I live because of the Father; so he that eateth me, he also shall live because of me. 58 This is the bread which came down out of heaven: not as the fathers ate, and died; he that eateth this bread shall live for ever.

Commentary on John 6:47-51
(Read John 6:47-51)
The advantage of the manna was small, it only referred to this life; but the living Bread is so excellent, that the man who feedeth on it shall never die. This bread is Christ's human nature, which he took to present to the Father, as a sacrifice for the sins of the world; to purchase all things pertaining to life and godliness, for sinners of every nation, who repent and believe in him.
Commentary on John 6:52-59
(Read John 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.
