1. John 10 does not say "will never".
What does Jesus say in John 10?
John 10:27-29 My sheep hear my voice, and I know them, and they follow me:
28 And I give unto them eternal life; and they shall never perish, neither shall any man pluck them out of my hand.
29 My Father, which gave them me, is greater than all; and no man is able to pluck them out of my Father's hand.
Concerning believers he says:
1. They are my sheep. It shows possession. He is not going to throw them away. They are too valuable; He paid the price of His blood for them.
2. He knows them. Why would he discard that which he knows? People don't sever relations with their "brothers," "friends," "children," etc. all terms which are used by Jesus in relation to those that believe on him.
3. They follow him. This is a characteristic of a true believer in Christ--one who has eternal life.
4. I give unto them eternal life. Now be honest. Does Jesus lie? Eternal means eternal. If eternal could stop it would be temporary. This is an irrefutable argument against one who believes they can lose their salvation. Either he has given us eternal salvation or he has lied. It is that simple. How can this point be refuted?
5. They
shall never perish. Bob castigates me because of my grammatical mistake when quoting from memory. Tell me Bob, is there any difference in meaning between "will never" and "shall never"?
6. No man shall pluck them out of my Father's hand. This is an emphatic promise that strengthens the promise of Jesus. If the OSAS promise given by Jesus isn't good enough for you then Jesus emphasizes it again saying if you don't believe me, my Father won't allow any of them to perish. They can't be plucked out of my Father's hand.
7. Again, he is emphatic about his father: "No man is able to pluck them out of my Father's hand." What a tremendous two-fold promise concerning His Father's protection for His disciples.
8. If that still wasn't good enough he then declares his deity be telling his disciples "I and my Father are one." He makes himself equal to God. The Jews understood exactly what he meant as they tried to stone him to death for the sin of blasphemy in that he made himself equal to God.
This is one of the strongest passages in the Bible, an irrefutable one, concerning the eternal security of the believer. To deny it would necessitate calling the integrity of the Lord Jesus Christ in question.
