Bible Truth Foundations
Part 1 of 3: New Life in Christ
Please begin by answering this question honestly in your own words.
After you have sinned or failed God in some way, what does your relationship with Him feel like? Do you feel you need to do something to get back to where you were?
Hebrews 10:14 (NKJV)
For by one offering He has perfected forever those who are being sanctified.
Two tenses in one sentence: "perfected forever" is complete; "being sanctified" is ongoing. Hold both as you read the teaching.
The central idea of this lesson
When a Christian sins, they do not lose their standing before God. What holds them is not their performance but their faith in Jesus Christ, whose one offering has perfected them forever. The New Covenant promise is that God will not impute their sins to their account.
Confidence Declaration
This lesson addresses one of the most debated questions in Christian theology: whether a believer's salvation is secure regardless of subsequent sin. The source material presents what is broadly called the eternal security position, also known as perseverance of the saints: that a genuine believer's standing before God is not destroyed by sin. This position is strongly held in Reformed, Baptist and many evangelical traditions. The Arminian or Wesleyan position, held in Methodist, many Pentecostal and other traditions, argues that salvation can be forfeited through deliberate apostasy or persistent unrepentant sin. This lesson teaches from the eternal security framework, rooted in the New Covenant passages of Hebrews and Romans 4. Where you land on this question is worth exploring with your church leaders. What the lesson does not dispute, and what all major traditions agree on, is this: sin has consequences; it is not to be treated lightly; and the right response to sin is always confession, repentance and returning to God.
Every believer who takes their faith seriously will, at some point, sin and then ask a version of this question: am I still saved? Do I need to start over? Has everything I received from God been forfeited? These are not hypothetical concerns; they are the lived reality of the Christian life, and they deserve a direct biblical answer rather than reassurance without substance.
The starting point is an honest acknowledgement that Christians do sin. The Apostle John, writing to believers, was explicit:
1 John 1:8–9 (NKJV)
If we say that we have no sin, we deceive ourselves, and the truth is not in us. If we confess our sins, He is faithful and just to forgive us our sins and to cleanse us from all unrighteousness.
John is addressing believers. He assumes they will sin. He does not say "if you sin, you are no longer a believer." He says "if we confess our sins, He is faithful and just to forgive." The provision for ongoing sin in the believer's life is built into the New Covenant. The question is not whether forgiveness is available; it is what the basis of that forgiveness is.
Note
The word "confess" in 1 John 1:9 is the Greek homologeo, meaning to say the same thing as, to agree with. To confess sin is not primarily to feel bad about it, though genuine sorrow is appropriate. It is to agree with God about it: to see it as He sees it, name it honestly and bring it to His faithfulness rather than hiding it. The basis for His forgiveness is not the depth of your remorse but His own character: "He is faithful and just." The promise is unconditional in its scope: all unrighteousness.
The core question is this: what keeps the believer in right standing with God? If the answer is "their own performance," then every sin potentially destroys that standing, and there is no real security at all. If the answer is "faith in what Jesus has done," then the standing is as secure as the object of faith, which does not change.
Romans 4 addresses this directly through the example of Abraham:
Romans 4:3–5 (NKJV)
For what does the Scripture say? "Abraham believed God, and it was accounted to him for righteousness." Now to him who works, the wages are not counted as grace but as debt. But to him who does not work but believes on Him who justifies the ungodly, his faith is accounted for righteousness.
The mechanism is faith, not works. If righteousness were credited on the basis of performance, it could also be debited on the basis of failure, which is exactly the anxiety that torments many believers. But because it is credited as grace through faith, the credit does not operate like a wages system. A gift cannot be repossessed on the same terms as a wage.
Romans 4:6–8 (NKJV)
Just as David also describes the blessedness of the man to whom God imputes righteousness apart from works: "Blessed are those whose lawless deeds are forgiven, and whose sins are covered; blessed is the man to whom the LORD shall not impute sin."
Paul quotes David's description of the person God pronounces blessed. Notice the final phrase: "the LORD shall not impute sin." In the original Greek of the New Testament, this is an emphatic negative: not "He may not" or "He sometimes does not," but He will never, not ever impute sin to this person's account. This is the New Covenant standing of the believer in Christ: their sins are not being charged to them. Their account reads righteous because that is what was credited to it at the moment of faith, and the credit does not reverse with each failure.
Going Deeper
Hebrews 10:16-17 (NKJV) quotes Jeremiah's New Covenant promise directly: "This is the covenant that I will make with them after those days, says the LORD: I will put My laws into their hearts, and in their minds I will write them, then He adds, 'Their sins and their lawless deeds I will remember no more.'" The phrase "remember no more" is not saying that God loses the information. It is covenantal language meaning He will not bring the matter up again, will not act on it, will not use it as a basis for judgment. The New Covenant deliberately includes this element: God's side of the agreement includes a commitment not to hold the believer's sin record against them. This is not because sin is unimportant; it is because sin's penalty has already been fully borne by Christ.
The key scripture for this lesson carries the full weight of the New Covenant argument in a single sentence:
Hebrews 10:14 (NKJV)
For by one offering He has perfected forever those who are being sanctified.
Two tenses held together deliberately. "Perfected forever" is a completed action: the standing before God is settled by Christ's one offering and does not need to be repeated or topped up. "Being sanctified" is present progressive: the process of growing in holiness is ongoing and real. The two are not in tension; they operate in different dimensions. Your standing before God is perfected and complete. Your progressive transformation into the character of Christ is ongoing and will be completed in glory. The first does not wait for the second to finish.
Note
The word "perfected" in Hebrews 10:14 is teleioo in Greek, meaning to bring to completion or fulfilment, to make fully adequate for the purpose. This is not a statement about moral perfection in behaviour; it is a statement about standing: the believer is fully adequate before God through the one offering of Christ. This is why the writer of Hebrews can then say in verse 22: "Let us draw near with a true heart in full assurance of faith." The assurance is not based on having performed adequately; it is based on the offering that has already made the believer adequate.
If sin does not destroy the believer's standing before God, what does it do? This is the right question to ask, and it prevents the lesson from being misread as a licence for careless living.
Sin damages fellowship. The relationship remains intact; the quality of the walk is disrupted. A child who behaves wrongly is still their parent's child; but something in the relationship suffers until it is addressed. First John 1:9 addresses this: confession restores the experience of fellowship and cleansing, even though the standing itself was never revoked.
Sin has consequences. The New Testament is frank about this. Galatians 6:7-8 (NKJV) states: "Do not be deceived, God is not mocked; for whatever a man sows, that he will also reap. For he who sows to his flesh will of the flesh reap corruption, but he who sows to the Spirit will of the Spirit reap everlasting life." Sin in the believer's life produces real damage: in relationships, in character, in capacity for fruitfulness, in the health of the soul. The security of the standing does not eliminate the consequences in the life.
Sin grieves the Holy Spirit. Ephesians 4:30 (NKJV) is direct: "And do not grieve the Holy Spirit of God, by whom you were sealed for the day of redemption." Notice: the seal is for the day of redemption; the sealing is not undone by sin. But the Spirit, who now dwells in the believer, can be grieved. That grief is itself a gift: it is the response of someone who cares about you deeply and who takes seriously what sin does to you and those around you.
Caution
This lesson must not be read as teaching that sin does not matter, or that the believer's response to sin is irrelevant. Romans 6:1-2 (NKJV) addresses that misreading head-on: "What shall we say then? Shall we continue in sin that grace may abound? Certainly not! How shall we who died to sin live any longer in it?" The security of the believer's standing is not a reason for carelessness about sin; it is the very thing that frees a person from having to perform to maintain their standing, which means their motive for holy living shifts from fear to love. That shift produces better and more sustainable transformation, not worse. The Christian who sins should confess honestly, receive the forgiveness that is already promised and return to God immediately, not after a period of self-imposed penance.
Practical Tip
When you sin, your instinct may be to wait: to feel sufficiently sorry, to do penance of some kind, to earn the right to come back to God. Resist that instinct. It is not faith in what Christ has done; it is an attempt to supplement it with your own suffering. Romans 4:8 says God shall not impute sin to your account. First John 1:9 says He is faithful and just to forgive when you confess. Bring the sin to God immediately, name it honestly and receive what is already promised. Then get up and continue walking. The longer the delay between the sin and the return, the more ground the enemy gains in your thinking.

| Question | My Answer | Group Discussion Notes |
|---|---|---|
| Read 1 John 1:8-9. John is writing to believers. What does the presence of this verse in a letter to Christians tell you about whether sin in the believer's life is expected? | ||
| Read Romans 4:3-5. What was credited to Abraham, and on what basis? If righteousness is credited as grace rather than as wages, what does that mean for whether failure can cancel it? | ||
| Read Romans 4:6-8. The source material notes that "the Lord shall not impute sin" is an emphatic negative in Greek, meaning He will never impute sin. How does the absolute language of that promise change your understanding of what happens when you sin? | ||
| Read Hebrews 10:14. Two tenses appear: "perfected forever" and "being sanctified." What is the difference between these two realities, and why is it important that both are present in the same sentence? | ||
| Read Romans 6:1-2. Paul anticipates the misuse of the grace teaching immediately. In your own words, why does the security of the believer's standing before God not lead to carelessness about sin? |
These questions are designed for open conversation at any level of experience. There are no trick questions and no single correct answer.
The truth of this lesson becomes most important in the moments directly after failure. These applications focus on what to do in those moments rather than in the calm of a study session.
| Context | How I Apply This |
|---|---|
| Immediately after sin | Refuse the instinct to delay. The enemy's strategy after a believer sins is to use the sin as a lever to increase distance from God: shame, self-imposed exile, endless self-recrimination before you allow yourself to come back. None of that is in 1 John 1:9. Confess immediately, receive the cleansing that is already promised and continue. The faster the return, the less ground is lost. |
| With persistent patterns | Hebrews 10:14 says you are perfected forever and being sanctified: standing complete, transformation ongoing. If there is a persistent pattern of sin in your life, the long-term strategy is not more guilt but more renewal of the mind (Ephesians 4:23). What you fill your attention with is what you move toward. Bring the pattern honestly to God, confess it, and ask specifically for help in renewing the thinking that feeds it. Santification is real work; it simply does not operate by threatening your standing. |
| With others who have fallen | Galatians 6:1 (NKJV) addresses this directly: "Brethren, if a man is overtaken in any trespass, you who are spiritual restore such a one in a spirit of gentleness, considering yourself lest you also be tempted." The instruction is restoration, not condemnation. The ground you stand on when you help someone who has sinned is the same ground they stand on: the one offering of Christ that has perfected you both forever. Let that inform the spirit in which you approach them. |
