53 Then Jesus said to them, Truly I say to you, If you do not take the flesh of the Son of man for food, and if you do not take his blood for drink, you have no life in you. 54 He who takes my flesh for food and my blood for drink has eternal life: and I will take him up from the dead at the last day. 55 My flesh is true food and my blood is true drink. 56 He who takes my flesh for food and my blood for drink is in me and I in him. 57 As the living Father has sent me, and I have life because of the Father, even so he who takes me for his food will have life because of me.
Matthew Henry's Commentary on John 6:53-57
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.
