Have No Fear
I am writing this for Christians who struggle with the thought of losing their salvation.
Several years ago a Christian lady came to me in distress. She was crying and had been up all night torturing herself thinking she had lost her salvation. She had been raised in a denomination that taught a person could lose their salvation. This lady had committed adultery many years before this when she was young girl. She had no doubt that she had been saved at the age of 14. But for the last 20 or so years she had lived with guilt, shame and the thought of going to hell. I told her that if she was truly saved before she committed adultery she is still saved today. I told her that King David had committed adultery but repented and was forgiven. He never stopped being a son of God. The prodigal son went from the Father's house and lived a life that took him to the pig pen. But he never stopped being a son.
She asked me if I had one passage of Scripture that proves the security of the believer for today. I said to her, I have a lot more than one but we will concentrate on one passage with 3 verses. The person who asked used the words once saved always saved and not the security of the believer. They both mean the same thing, once a person truly believes in Christ, they are eternally secure or always saved. You can't get unsaved no matter what you do! This is basically what I gave the lady.
There are so many verses I could give you but here are 3 verses which teach the undeniable truth concerning the security of the believer. John 10:27-29–My sheep hear my voice, and I know them, and they follow me. And I give unto them eternal life; and they shall never perish, neither shall any man pluck them out of my hand My Father, which gave them me, is greater than all; and no man is able to pluck them out of my Father's hand.
I don't know for certain but I would guess that these three verses are the most often used verses to support the doctrine of the eternal security of the believer. I want you to notice that four times in these three verses Jesus gives the idea that His sheep will never be lost:
1. I give unto them eternal life (v. 28)
2. They shall never perish (v. 28)
3. Neither shall any man pluck them out of my hand (v. 28)
4. No man is able to pluck them out of my Father's hand (v. 29)
These references to the security of the sheep cannot be ignored. When Jesus Christ says that no man can pluck them out of His hand and that no man is able to pluck them out of His Father's hand and that He and His Father are one (v. 30), He is making the strongest possible statement that could ever be made concerning the security of the sheep.
Who are the sheep? The context of this passage clearly reveals that those who genuinely believe in the Lord Jesus Christ are the sheep. Verse 26 tells us that the Pharisees were not the sheep because they "[believed] not." The sheep to which Jesus refers in this text are those who truly believe in Jesus Christ as the Messiah. They became sheep by believing, not by performing any particular work of their own accord.
After Jesus made it clear that the sheep are only those who believe in Christ, He then mentions four times that those sheep have eternal life and cannot lose that eternal life no matter what they do.
There are those who agree that NO MAN can pluck them out of the Father's hand but they teach that a person can pluck himself out of the Father's hand through his own sins. My come back to that is this, look what Jesus says "no man" two times in these verses and expresses those statements with the idea that His sheep shall never perish. My conclusion is that Jesus also includes the believer himself as part of the "no man" who possesses the ability to pluck a believer out of the Father's hand. When Jesus Christ says no man can cause a believer to lose his salvation, He includes every man-even the individual who committed the sin.
Another aspect of these verses that proves the sheep are eternally secure is found in the phrase "no man is able." The power of God to save and to keep the one who comes to Him through Christ is a sufficient basis for our security. No man has the ability to snatch the sheep from God's hand due to a lack of power. God is all powerful and nothing or no one is more powerful than Him. You are in His hands and no sin, person or thing can take what belongs to Him from His hand. Hope this helps someone. God Bless!
