41 Then the people began to murmur in disagreement because he had said, "I am the bread that came down from heaven." 42 They said, "Isn't this Jesus, the son of Joseph? We know his father and mother. How can he say, 'I came down from heaven'?" 43 But Jesus replied, "Stop complaining about what I said. 44 For no one can come to me unless the Father who sent me draws them to me, and at the last day I will raise them up. 45 As it is written in the Scriptures, 'They will all be taught by God.' Everyone who listens to the Father and learns from him comes to me. 46 (Not that anyone has ever seen the Father; only I, who was sent from God, have seen him.) 47 "I tell you the truth, anyone who believes has eternal life. 48 Yes, I am the bread of life! 49 Your ancestors ate manna in the wilderness, but they all died. 50 Anyone who eats the bread from heaven, however, will never die. 51 I am the living bread that came down from heaven. Anyone who eats this bread will live forever; and this bread, which I will offer so the world may live, is my flesh."

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.
