Really is that why his Apostles followed him, or was it because of the truths he spoke, as Peter stated: John 6:68 ...
to whom shall we go? thou hast the words of eternal life.
47Verily, verily, I say unto you,
He that believeth on me hath everlasting life. 53
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.
63 ...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.
Notice Jesus states:
54Whoso eateth my flesh, and drinketh my blood, hath eternal life; and before that he states:
He that believeth on me hath everlasting life. And then he states: 63 ...
the words that I speak unto you, they are... life. Then Peter states: 68 ...
thou hast the words of eternal life.
Conclusion:to believe in Christ is to embrace the words of Christ and to embrace the words of Christ is to eat Christ's flesh and posses Eternal life.
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.
Notice believing in christ, the words Jesus spoke and eating Jesus's flesh are all the same: life and life eternal.
