41 The Jews therefore murmured about him, because he said, I am the bread which has come down out of heaven. 42 And they said, Is not this Jesus the son of Joseph, whose father and mother we have known? how then does he say, I am come down out of heaven? 43 Jesus therefore answered and said to them, Murmur not among yourselves. 44 No one can come to me except the Father who has sent me draw him, and I will raise him up in the last day. 45 It is written in the prophets, And they shall be all taught of God. Every one that has heard from the Father [himself], and has learned [of him], comes to me; 46 not that any one has seen the Father, except he who is of God, he has seen the Father. 47 Verily, verily, I say to you, He that believes [on me] has life eternal. 48 I am the bread of life. 49 Your fathers ate the manna in the wilderness and died. 50 This is the bread which comes down out of heaven, that one may eat of it and not die. 51 I am the living bread which has come down out of heaven: if any one shall have eaten of this bread he shall live for ever; but the bread withal which I shall give is my flesh, which I will give for the life of the world.
Matthew Henry's Commentary on John 6:41-51
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.
