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." 52 Then the people began arguing with each other about what he meant. "How can this man give us his flesh to eat?" they asked. 53 So Jesus said again, "I tell you the truth, unless you eat the flesh of the Son of Man and drink his blood, you cannot have eternal life within you. 54 But anyone who eats my flesh and drinks my blood has eternal life, and I will raise that person at the last day. 55 For my flesh is true food, and my blood is true drink. 56 Anyone who eats my flesh and drinks my blood remains in me, and I in him. 57 I live because of the living Father who sent me; in the same way, anyone who feeds on me will live because of me. 58 I am the true bread that came down from heaven. Anyone who eats this bread will not die as your ancestors did (even though they ate the manna) but will live forever."
Matthew Henry's Commentary on John 6:47-58
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.
