35And Jesus said unto them, I am the bread of life: he that cometh to me shall never hunger; and he that believeth on me shall never thirst. 36But I said unto you, That ye also have seen me, and believe not. 37All that the Father giveth me shall come to me; and him that cometh to me I will in no wise cast out. 38For I came down from heaven, not to do mine own will, but the will of him that sent me. 39And this is the Father's will which hath sent me, that of all which he hath given me I should lose nothing, but should raise it up again at the last day. 40And this is the will of him that sent me, that every one which seeth the Son, and believeth on him, may have everlasting life: and I will raise him up at the last day.
41The Jews then murmured at him, because he said, I am the bread which came down from heaven. 42And they said, Is not this Jesus, the son of Joseph, whose father and mother we know? how is it then that he saith, I came down from heaven? 43Jesus therefore answered and said unto them, Murmur not among yourselves. 44No man can come to me, except the Father which hath sent me draw him: and I will raise him up at the last day. 45It is written in the prophets, And they shall be all taught of God. Every man therefore that hath heard, and hath learned of the Father, cometh unto me. 46Not that any man hath seen the Father, save he which is of God, he hath seen the Father. 47Verily, verily, I say unto you, He that believeth on me hath everlasting life. 48I am that bread of life. 49Your fathers did eat manna in the wilderness, and are dead. 50This is the bread which cometh down from heaven, that a man may eat thereof, and not die. 51I am the living bread which came down from heaven: if any man eat of this bread, he shall live for ever: and the bread that I will give is my flesh, which I will give for the life of the world.
52The Jews therefore strove among themselves, saying, How can this man give us his flesh to eat? 53Then Jesus said unto them, Verily, verily, I say unto you, Except ye eat the flesh of the Son of man, and drink his blood, ye have no life in you. 54Whoso eateth my flesh, and drinketh my blood, hath eternal life; and I will raise him up at the last day. 55For my flesh is meat indeed, and my blood is drink indeed. 56He that eateth my flesh, and drinketh my blood, dwelleth in me, and I in him. 57As the living Father hath sent me, and I live by the Father: so he that eateth me, even he shall live by me. 58This is that bread which came down from heaven: not as your fathers did eat manna, and are dead: he that eateth of this bread shall live for ever.
59These things said he in the synagogue, as he taught in Capernaum.
60Many therefore of his disciples, when they had heard this, said, This is an hard saying; who can hear it? 61When Jesus knew in himself that his disciples murmured at it, he said unto them, Doth this offend you? 62What and if ye shall see the Son of man ascend up where he was before? 63It is the spirit that quickeneth; the flesh profiteth nothing: the words that I speak unto you, they are spirit, and they are life. 64But there are some of you that believe not. For Jesus knew from the beginning who they were that believed not, and who should betray him. 65And he said, Therefore said I unto you, that no man can come unto me, except it were given unto him of my Father.
66From that time many of his disciples went back, and walked no more with him. 67Then said Jesus unto the twelve, Will ye also go away? 68Then Simon Peter answered him, Lord, to whom shall we go? thou hast the words of eternal life. 69And we believe and are sure that thou art that Christ, the Son of the living God. 70Jesus answered them, Have not I chosen you twelve, and one of you is a devil? 71He spake of Judas Iscariot the son of Simon: for he it was that should betray him, being one of the twelve.
His flesh and his blood was the Word which he taught,
and he was the Word that he taught because he DID
what he said.
Likewise, it is expected of those who follow him to eat that flesh, and drink that blood, do what Jesus commanded.
