41 Now the Jews said bitter things about Jesus because of his words, I am the bread which came down from heaven. 42 And they said, Is not this Jesus, the son of Joseph, whose father and mother we have seen? How is it then that he now says, I have come down from heaven? 43 Jesus made answer and said, Do not say things against me, one to another. 44 No man is able to come to me if the Father who sent me does not give him the desire to come: and I will take him up from the dead on the last day. 45 The writings of the prophets say, And they will all have teaching from God. Everyone whose ears have been open to the teaching of the Father comes to me. 46 Not that anyone has ever seen the Father; only he who is from God, he has seen the Father. 47 Truly I say to you, He who has faith in me has eternal life. 48 I am the bread of life. 49 Your fathers took the manna in the waste land—and they are dead. 50 The bread which comes from heaven is such bread that a man may take it for food and never see death. 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.

Commentary on John 6:36-46
(Read John 6:36-46)
The discovery of their guilt, danger, and remedy, by the teaching of the Holy Spirit, makes men willing and glad to come, and to give up every thing which hinders applying to him for salvation. The Father's will is, that not one of those who were given to the Son, should be rejected or lost by him. No one will come, till Divine grace has subdued, and in part changed his heart; therefore no one who comes will ever be cast out. The gospel finds none willing to be saved in the humbling, holy manner, made known therein; but God draws with his word and the Holy Ghost; and man's duty is to hear and learn; that is to say, to receive the grace offered, and consent to the promise. None had seen the Father but his beloved Son; and the Jews must expect to be taught by his inward power upon their minds, and by his word, and the ministers whom he sent among them.
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.
