John 6:63 It is the spirit that quickeneth; the flesh profiteth nothing: the words that I speak unto you they are spirit, and they are life.
Jesus had just shocked the disciples by telling them they must eat his flesh and drink His blood. Now, I would have been shocked too. But Jesus was telling them a parable, because He couldn’t tell them the future yet. He is giving them a picture of the Spiritual Realm about to happen when He leaves this earthly vessel behind and they will understand the blood was the life of Flesh. The bread was Spirit. There had to be a crossover where death was destroyed and life eternal was taken up. Jesus had to die and be resurrected for death to lose it’s power. Life was in Jesus’s blood, physical life.
As the perfect sacrifice He had to die as a sinless flesh-man to be worthy for the Father to raise Him up victorious over the sentence of death. A cow didn’t sin – a man did. Only a man could pay the price for that sin to restore life eternal unto mankind. But there was no man worthy. All had sinned and come short of the glory of God. So God sent His Only Begotten Son that ALL might be saved. Choice. The Door was opened. It must be passed through.
How does this apply to the blood and the bread? How do we partake?
He gave us an example when He gave bread and wine to the disciples and said, Take, eat – Take, drink. He was showing them the symbols of remembrance. We read and learn the WORD and we pray and seek and PARTAKE OF THE SPIRIT OF OUR LIVING GOD.
