51 I am the living bread which has come from heaven: if any man takes this bread for food he will have life for ever: and more than this, the bread which I will give is my flesh which I will give for the life of the world. 52 Then the Jews had an angry discussion among themselves, saying, How is it possible for this man to give us his flesh for food? 53 Then Jesus said to them, Truly I say to you, If you do not take the flesh of the Son of man for food, and if you do not take his blood for drink, you have no life in you. 54 He who takes my flesh for food and my blood for drink has eternal life: and I will take him up from the dead at the last day. 55 My flesh is true food and my blood is true drink. 56 He who takes my flesh for food and my blood for drink is in me and I in him. 57 As the living Father has sent me, and I have life because of the Father, even so he who takes me for his food will have life because of me. 58 This is the bread which has come down from heaven. It is not like the food which your fathers had: they took of the manna, and are dead; but he who takes this bread for food will have life for ever. 59 Jesus said these things in the Synagogue while he was teaching at Capernaum.
60 Then, hearing this, a number of his disciples said, This is a hard saying; who is able to take in such teaching? 61 When Jesus became conscious that his disciples were protesting about what he said, he said to them, Does this give you trouble? 62 What then will you say if you see the Son of man going up to where he was before? 63 The spirit is the life giver; the flesh is of no value: the words which I have said to you are spirit and they are life. 64 But still some of you have no faith. For it was clear to Jesus from the first who they were who had no faith, and who it was who would be false to him. 65 And he said, This is why I said to you, No man is able to come to me if he is not given the power to do so by the Father. 66 Because of what he said, a number of the disciples went back and would no longer go with him.

(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.
Commentary on John 6:60-65
(Read John 6:60-65)
The human nature of Christ had not before been in heaven, but being God and man, that wondrous Person was truly said to have come down from heaven. The Messiah's kingdom was not of this world; and they were to understand by faith, what he had said of a spiritual living upon him, and his fulness. As without the soul of man the flesh is of no value, so without the quickening Spirit of God all forms of religion are dead and worthless. He who made this provision for our souls, alone can teach us these things, and draw us unto Christ, that we may live by faith in him. Let us apply to Christ, thankful that it is declared that every one who is willing to come unto him shall be made welcome.
Commentary on John 6:66-71
(Read John 6:66-71)
When we admit into our minds hard thoughts of the words and works of Jesus, we enter into temptation, which, if the Lord in mercy prevent not, will end in drawing back. The corrupt and wicked heart of man often makes that an occasion for offence, which is matter of the greatest comfort. Our Lord had, in the foregoing discourse, promised eternal life to his followers; the disciples fastened on that plain saying, and resolved to cleave to him, when others fastened on hard sayings, and forsook him. Christ's doctrine is the word of eternal life, therefore we must live and die by it. If we forsake Christ, we forsake our own mercies. They believed that this Jesus was the Messiah promised to their fathers, the Son of the living God. When we are tempted to backslide or turn away, it is good to remember first principles, and to keep to them. And let us ever remember our Lord's searching question; Shall we go away and forsake our Redeemer? To whom can we go? He alone can give salvation by the forgiveness of sins. And this alone brings confidence, comfort, and joy, and bids fear and despondency flee away. It gains the only solid happiness in this world, and opens a way to the happiness of the next.
