Being confident of this very thing, that he which hath begun a good work in you will perform it until the day of Jesus Christ:
Introduction
The doctrine of eternal security, often summarized as “Once Saved, Always Saved,” is a cornerstone of Biblical truth. It assures the believer that once they are genuinely saved by grace through faith in Jesus Christ, their salvation is eternally secure and cannot be lost.
This doctrine is not based on human reasoning or tradition but is firmly rooted in the Word of God. It emphasizes God’s faithfulness, the finished work of Jesus Christ on the cross, and the sealing power of the Holy Spirit. Let us explore this comforting truth by diving into the Holy Scriptures.
1. Salvation is God’s Work, Not Ours
1.1 Salvation is By Grace Through Faith
The foundation of eternal security begins with understanding that salvation is entirely God’s work. It is not something we earn through good works or maintain by our own strength.
Ephesians 2:8-9 (KJV) states:
“For by grace are ye saved through faith; and that not of yourselves: it is the gift of God: Not of works, lest any man should boast.”
If salvation is a gift from God, then it follows that the maintenance of that gift is not dependent on human effort. God’s grace, not human works, is what saves and keeps a person secure in Christ.
1.2 The Finished Work of Christ on the Cross
When Jesus Christ died on the cross, He declared, “It is finished” (John 19:30). His atonement was complete, and nothing more could be added to it.
Hebrews 10:14 (KJV) confirms:
“For by one offering he hath perfected for ever them that are sanctified.”
The believer’s salvation is secured by the once-for-all sacrifice of Jesus Christ. If the work of salvation is complete and perfect, how can a believer add to or take away from it?
2. God’s Promises to Preserve the Believer
2.1 God’s Promise of Eternal Life
John 10:27-29 (KJV) is a key passage that illustrates the eternal security of the believer:
“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.”
Notice the key phrases:
“I give unto them eternal life” – Salvation is a gift from Christ Himself.
“They shall never perish” – This is a direct promise that a true believer will never lose their salvation.
“No man can pluck them out of my hand” – The believer is held securely by both Christ and the Father.
2.2 Sealed by the Holy Spirit
The Bible teaches that the believer is sealed by the Holy Spirit, a mark of ownership and security.
Ephesians 1:13-14 (KJV) says:
“In whom ye also trusted, after that ye heard the word of truth, the gospel of your salvation: in whom also after that ye believed, ye were sealed with that holy Spirit of promise, Which is the earnest of our inheritance until the redemption of the purchased possession, unto the praise of his glory.”
This seal is a guarantee that God will bring His work of salvation to completion.
Philippians 1:6 (KJV) echoes this promise:
“Being confident of this very thing, that he which hath begun a good work in you will perform it until the day of Jesus Christ.”
2.3 Eternal Security in Romans 8
Romans 8 is a powerful chapter that solidifies the doctrine of eternal security.
Romans 8:38-39 (KJV) declares:
“For I am persuaded, that neither death, nor life, nor angels, nor principalities, nor powers, nor things present, nor things to come, Nor height, nor depth, nor any other creature, shall be able to separate us from the love of God, which is in Christ Jesus our Lord.”
Paul makes it clear that nothing in all of creation can separate the believer from God’s love, which is found in Christ Jesus.
3. Common Objections to Eternal Security
Many who oppose the doctrine of eternal security raise objections, often misinterpreting Scripture. Let us address a few common arguments.
3.1 “What About Falling Away?”
Some cite Hebrews 6:4-6 to argue that a believer can fall away from grace. However, this passage must be understood in its context.
Hebrews 6:9 (KJV) clarifies:
“But, beloved, we are persuaded better things of you, and things that accompany salvation, though we thus speak.”
The writer is speaking of those who have never truly been saved.
3.2 “What About Backsliders?”
The Bible teaches that true believers may backslide, but they will never lose their salvation. God chastens His children to bring them back to Him.
Hebrews 12:6 (KJV) says:
“For whom the Lord loveth he chasteneth, and scourgeth every son whom he receiveth.”
4. Practical Implications of Eternal Security
Understanding the eternal security of the believer brings peace and assurance to the Christian life.
4.1 Assurance of Salvation
1 John 5:13 (KJV) assures us:
“These things have I written unto you that believe on the name of the Son of God; that ye may know that ye have eternal life, and that ye may believe on the name of the Son of God.”
4.2 Motivation for Holy Living
The doctrine of eternal security does not encourage sin. Instead, it motivates believers to live for Christ out of gratitude.
Titus 2:11-12 (KJV) teaches:
“For the grace of God that bringeth salvation hath appeared to all men, Teaching us that, denying ungodliness and worldly lusts, we should live soberly, righteously, and godly, in this present world.”
If you can lose it, you are not saved. If you think you can lose it you are not putting your faith and trust in the finished work of the Lord Jesus Christ (and are this not saved.) Repent and Believe.
The doctrine of eternal security is a glorious truth rooted in God’s faithfulness, the finished work of Christ, and the sealing power of the Holy Spirit. It brings peace, assurance, and motivation for holy living.
