The Bible is correct, not man.
Heb 6 through 10 makes it clear, to fall away is deadly, spiritually if we choose to do so.
We cannot be plucked out of His hand, and nothing can separate us from the love of God, but nowhere does it say or imply, we cannot fall away of our own inclination if we so chose.
God told Moses, the one who sins will be blotted out of the book of life. Exodus 32:33
The worst part of Calvinism is the belief that a God who is love, created, gave life to, and protected the vast majority of humanity, to be lost, doomed and damned forever.
This heretical doctrine Calvin invented, claims God alone chooses who will be saved, and who will be damned in the lake of fire, man has no choice in the matter.
That is not the God who saved me.
Calvinism back-channels works into salvation, saying that a Christian who perseveres in faith unto the end is saved, that it is based upon that person's ability to "endure until the end." That is the doctrine called "Perseverance of the Saints." I do not believe in this doctrine.
The doctrine I believe in, and what the Bible teaches, is called "Eternal Security," which states that the man who is saved is sealed of the Holy Spirit upon believing and receiving the Gospel of Jesus Christ (Ephesians 1:13), and that the seal upon the believer is the seal made by God, and lasts until the day of redemption (Ephesians 4:30); such a seal cannot be broken by any man, whether it be the believer or not, because no man can make crooked that which God has made straight (Ecclesiastes 7:13), and no man can shut the door that Jesus opens (Revelation 3:7). If what you say is true, and the believer can somehow cause himself to become unsaved, then you are saying that that same believer is more powerful then God, and is able to break the seal of the Holy Ghost given to him by God. And that, sir, is blasphemy.
Secondly, Jesus says very clearly in John 10:28 that
no man can pluck those who believe in him out his hand, and that includes the man who believes. No man means no man, sir. You cannot have it both ways; the verse says what it means.
Thirdly, in Exodus, we cannot apply that verse to the context of the "Book of Life," which is the book containing all the souls who shall receive everlasting life from the Lord. Why not, you may ask? Because upon comparing scripture with scripture, we find that in Deuteronomy 9:18-26, the context of Moses begging the Lord not to bring wrath upon the people has nothing to do with individual's having salvation, but rather about the success of the nation of Israel as a people. They were rebelling against God, committing wicked idolatry in the wilderness, and were not serving the Lord as they ought to have, and so God wanted to destroy them in the wilderness, and utterly wipe away their inheritance, as proven in Deuteronomy 9:26. What was their inheritance? The land of Canaan, promised to Abraham, the land "flowing with milk and honey;" God wanted to revoke that inheritance from them and cause them to be a people no longer, but God spared them for Moses' sake. This is not talking about being wiped from the book of life if one sinned against God; this was talking about being destroyed as a nation.
Fourthly, all have sinned and come short of the glory of God (Romans 3:23); therefore, no person who has ever lived (except for Jesus) has deserved everlasting life, which is why God offers it as a gift (Ephesians 2:8, Romans 5:18, Romans 6:23) to all who believe (John 3:16-18); those who believe receive it, not because they were ever worthy, but because they place their trust in Christ, the one who alone is worthy. Therefore, why would God take away something from a person they never deserved to have in the first place? He wouldn't, because other it wouldn't be a free gift. The idea of a gift is that it is bought and paid for by the giver (Christ), and given to be possessed by the receiver. That means that the receiver gets to keep it as his own without conditions, otherwise it wouldn't be a gift - it would be a loan. If you say that salvation is not a free gift, you are calling God a liar, but God cannot lie (Titus 1:2), because he offers salvation as a promise based upon his own righteousness.
Hebrews 10:29 in context is speaking of he who is not saved. At the end of the chapter, the writer of Hebrews makes the distinction between he who is just, and he who draws back unto perdition. He who is just lives by faith, and believes unto the saving of the soul. He who draws back did not believe, and draws back unto perdition. That person is the one talked about in verse 29. Why? Because there remaineth no more sacrifice for sins (Hebrews 10:26); he that does not have the sacrifice of sins accounted unto him is not saved, period. Because the person who has their sins remitted, there is no more offering for sin (Hebrews 10:18) because their sins are remitted already by the blood of Jesus.
Hebrews 6:4 says it is impossible for those who were once enlightened, and made partakers of the holy Ghost to be renewed. Why? Because those people are already renewed, because they have been sealed (Ephesians 1:13). If they had to be renewed again, and were to be re-saved again upon repentance, it would show the insufficiency of the sacrifice of Jesus. It would show that he wouldn't be a good enough atonement, and that his righteousness was fallible due to the fact of the person having to be re-saved, which would put him to an open shame. However, we know that that is impossible (verse 4), because Christ was offered once for sins (Hebrews 9:24-28); he is totally sufficient to pay for the sins of the world (1 John 2:2). If you interpret this verse the way you do, then it contradicts many other obvious scriptures saying a person who receives eternal life will never die (John 5:24, John 6:47, John 3:18), but God's way is perfect (Psalms 18:30), and his scripture wouldn't contradict itself.
The fact of the matter is, if you believe that God will ever take away your salvation, you're not trusting God; if you believe that you must do anything to keep your salvation, you are trusting yourself, a sinner, to be righteous enough to get to heaven. However, there is none righteous, not even one (Romans 3:10); therefore, upon receiving salvation, it is only logical to conclude that one cannot lose that which he never deserved to receive in the first place, no matter what, because God does not change his mind about something so serious. Man is not greater than God, and man cannot undo that which God has finished. Biblically, it only makes sense that one who receives Christ forever has Christ.
The people who deny everlasting life are those who do not trust God. Period.
