Jesus explains that if we obey his words then it is eating him, and his words are Spirit and life.
If anyone eats of this bread, he will live forever, John 6:51. This bread is Jesus’ flesh, which he will give for the life of the world, John 6:53.
Unless we eat the flesh of the Son of Man and drink his blood, we have no life in us. Jesus tells us the truth, if anyone obeys his word, he will never see death, John 8:51.
I suppose you are still thinking along the lines of transubstantiation which makes you a RC cannibal.
