As Joh 6:45 shows us those that hear and learn from the Father in other words hear and believe the gospel message etc will be given to Christ. If they do not believe even through they have heard they will not be given to Christ. Is that what you believe?
Nobody, I say nobody, understood what Jesus meant when he dealt with the Jews in Caperaum in John 6. When the gospel accounts closed with the death of Jesus Christ, not a single person believed he would die and rise from the dead. Not even one. Logic and reason from the scriptures teaches those of us who read and study the scriptures instead of people who have begun religious movements based on unorthodox dictionaries that they have created in their own minds.
Those who came to him came to him believing two things about him that were required for them to be his, but they did not have any faith in the gospel that saves all men everywhere, and that is defined in 1 Cor 15: 1-4. It is the death, burial, and resurrection of Jesus Christ. Nobody preached that during the ministry of Jesus Christ, not even Jesus himself.
The two things that were required of Israel only is that they believe that he is the son of God and the second thing is that he is the Messiah that had been promised to Israel.
The blindness of Calvinism and hyper Calvinism is self inflicted. It is a failure of logic and reason and faith in what God has said and revealed about himself and us. It is an introduction of a new way to read scripture. It is unbelief.
Jesus would have a prophecy for Capernaum later when he addressed this crowd. Here it is.
John 6:17
And entered into a ship, and went over the sea toward
Capernaum. And it was now dark, and Jesus was not come to them.
Mt 11:23 And thou, Capernaum, which art exalted unto heaven, shalt be brought down to hell: for if the mighty works (like feeding 5,000 and walking on water), which have been done in thee, had been done in Sodom, it would have remained until this day. 24 But I say unto you, That it shall be more tolerable for the land of Sodom in the day of judgment, than for thee.
Peter got what Jesus was teaching and what he was requiring his followers to believe, that he was the Messiah and the son of God; He said so.
Jn 6:66 From that time many of his disciples went back, and walked no more with him.
67 Then said Jesus unto the twelve, Will ye also go away?
68 Then Simon Peter answered him, Lord, to whom shall we go? thou hast the words of eternal life.
69 And we believe and are sure that thou art that Christ, the Son of the living God.
Here is what Peter said some time later when Jesus asked him to believe something that was not required but just information at that time and something he had not told him previously.
Mt 16:15 He saith unto them, But whom say ye that I am?
16 And Simon Peter answered and said, Thou art the Christ, the Son of the living God.
Okay, so far so good.
21 From that time forth began Jesus to shew unto his disciples, how that he must go unto Jerusalem, and suffer many things of the elders and chief priests and scribes, and be killed, and be raised again the third day.
Peter's reaction to this gospel: Total rejection, enough to rebuke God.
22 Then Peter took him, and began to rebuke him, saying, Be it far from thee, Lord: this shall not be unto thee.
Back to what Jesus said
Mt 16: 23 But he turned, and said unto Peter, Get thee behind me, Satan: thou art an offence unto me: for thou savourest not the things that be of God, but those that be of men.
Even later; some new information and his disciples reaction;
22 And while they abode in Galilee, Jesus said unto them, The Son of man shall be betrayed into the hands of men:
23 And they shall kill him, and the third day he shall be raised again. And they were exceeding sorry.
Mark would report it this way;
31 For he taught his disciples, and said unto them, The Son of man is delivered into the hands of men, and they shall kill him; and after that he is killed, he shall rise the third day.
32 But they understood not that saying, and were afraid to ask him.
Logic, reason, faith, context. preparation, prophecy the unfolding redemptive plan of God goes a long way in understanding the mind of God and how he thinks. His plan is made know to us through words, not visions and dreams and special revelations. We must believe his words and we must refrain from twisting them to suit our own lusts.
Everyone since the cross is required to believe the gospel of Jesus Christ as defined in 1 Cor 15 now or they will not be saved and receive the gift of God, which is his Spirit and eternal life..
Than you Heavenly Father for you great salvation through your son Jesus Christ.
