35 And Jesus said to them: "I am the bread of life. He that comes to me shall
not hunger, and he that believes in me shall never thirst.
36 But I said unto you that you also have seen me, and you believe not.
37 All that the Father gives to me shall come to me — and him that comes
to me, I will not cast out.
38 Because I came down from heaven, not to do
my own will but the will of him that sent me.
39 Now this is the will of the Father who sent me: that of all that he has
given me, I should lose nothing; but should raise it up again in the last day.
40 And this is the will of my Father that sent me: that every one who sees
the Son and believes in him may have life everlasting. And I will raise him
up in the last day."
41 The Jews therefore murmured at him, because he had said: "I am the
living bread which came down from heaven."
( This has nothing to do with manna of the desert, the stuff they ate
was for food only.)
42 And they said: "Is not this Jesus, the son of Joseph, whose father and
mother we know? How then says he: 'I came down from heaven?'"
( It was hard for many to believe what Jesus was saying, many did believe
the words of Jesus because they knew he is the messiah. Many today say
they don't believe Jesus because,,,??? )
43 Jesus therefore answered and said to them:
"Murmur not among yourselves.
44 No man can come to me, unless the Father, who has sent me, draws him.
And I will raise him up in the last day.
45 It is written in the prophets: 'And they shall all be taught of God.' Every
one that has heard of the Father and has learned comes forth me.
46 Not that any man has seen the Father; but he who is of God, he has
seen the Father.
47 Amen, amen, I say unto you: He that believes in me has everlasting life.
48 I am the bread of life.
49 Your fathers ate manna in the desert, and are dead.
50 This is the bread which comes down from heaven: that if any man eat
of it, he may not die.
51 I 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,
for the life of the world."
( What is called the Holy Eucharist is a precept, a gift from the Father
through Jesus that will be here for us until the last days.
There isn't anything in John 6 that says - once saved, always saved.
Nor is there anything in the complete Bible that teaches it.)
