50 But now here is Bread that truly comes down out of heaven. Anyone eating this Bread will not die, ever. 51 I am the Bread - living Bread! - who came down out of heaven. Anyone who eats this Bread will live - and forever! The Bread that I present to the world so that it can eat and live is myself, this flesh-and-blood self." 52 At this, the Jews started fighting among themselves: "How can this man serve up his flesh for a meal?" 53 But Jesus didn't give an inch. "Only insofar as you eat and drink flesh and blood, the flesh and blood of the Son of Man, do you have life within you. 54 The one who brings a hearty appetite to this eating and drinking has eternal life and will be fit and ready for the Final Day. 55 My flesh is real food and my blood is real drink. 56 By eating my flesh and drinking my blood you enter into me and I into you.

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.
