In Defense of OSAS – Why "Once Saved, Always Saved" Is the Heart of the Gospel

[Eternally Grateful]

If forsaking our sins means sinless perfection, then 1 John 1:8-10 is superfluous. Proverbs 28:13 is an exhortation for believers to confess and forsake their sins, acknowledging their need for God's grace and mercy in their struggle against sin, rather than promoting the idea they can and must achieve sinless perfection in this life.

Notice that - "If we confess our sins, he is faithful and just to forgive us our sins, and to cleanse us from all unrighteousness" (1 John 1:9) is in contrast to - If we say that we have no sin, (present tense) we deceive ourselves, and the truth is not in us (1 John 1:8) and - If we say that we have not sinned, (past tense) we make him a liar, and his word is not in us. (1 John 1:10)

Certain folks seem to misunderstand verse 9 to mean that we "must confess each and every sin that we commit as we commit them" (keep a specific inventory of every sin) as an "additional requirement" to "remain cleansed" and "if we forget a sin, we are toast!" Who could actually write an exhaustive list of every sin they have ever committed or ever will commit? Sin is not only missing the mark by what we do but also what we fail to do. (James 4:17)

Believers "confess" (Greek - homologeó) speak the same/acknowledge/agree with God's perspective about their sins and have a settled recognition and ongoing acknowledgment that one is a sinner in need of cleansing and forgiveness in contrast with saying that we have no sin or that we have not sinned. (1 John 1:8-10)

In regard to Hebrews 10:26, to "sin willfully" in the Greek carries the idea of deliberate intention that is habitual, which stems from rejecting Christ deliberately. This is continuous action, a matter of practice. Now we don't walk along our daily life and "accidentally" fall into a pit called sin. We exercise our will but, the use of the participle clearly shows a ongoing, willful, habitual action. The unrighteous practice sin (1 Corinthians 6:9-10; Galatians 5:19-21); not the righteous, who are born of God (1 Corinthians 6:11; 1 John 3:9). *Hermeneutics.

If the word 'sanctified' in Hebrews 10:29 is used to describe saved people who lost their salvation as eternal IN-securists teach, then we have a contradiction because the writer of Hebrews in verse 10 said "sanctified through the offering of the body of Jesus Christ once for all" (Hebrews 10:10) and in verse 14, we read, "perfected for all time those who are sanctified." (Hebrews 10:14) So, in Hebrews 10:10, we clearly read ..WE have been sanctified through the offering of the body of Jesus Christ once for all. In Hebrews 10:14, we read - For by one offering He has perfected for all time THOSE who are sanctified. To go from sanctified back to un-sanctified would be in contradiction here.

*NOWHERE in the context does it specifically say the person who "trampled under foot the Son of God, and has regarded as unclean the blood of the covenant" was "saved" and/or "lost their salvation." The reference to "the blood of the covenant that sanctified him" in verse 29 "on the surface" appears to be referring to a Christian, but this overlooks the fact that the word translated "sanctified" (which is the verb form of the adjective "holy") which means "set apart," and doesn't necessarily refer to salvation.

Strong's Concordance
hagiazó: to make holy, consecrate, sanctify
Original Word: ἁγιάζω
Part of Speech: Verb
Transliteration: hagiazó
Phonetic Spelling: (hag-ee-ad'-zo)
Definition: to make holy, consecrate, sanctify
Usage: I make holy, treat as holy, set apart as holy, sanctify, hallow, purify.

*In 1 Corinthians 7:14, Paul uses it to specifically refer to non-Christians who are "sanctified" or "set apart" by their believing spouse. (And by this Paul does not mean that they are saved). A non-Christian can be "set apart" from other non-Christians without experiencing salvation as Paul explained. So the word "sanctified" means to be "set apart." If the word "sanctified" simply meant saved, then you would have to say that the seventh day was saved (Genesis 2:3), the tabernacle was saved (Exodus 29:43), Moses saved the people after coming down off the mountain (Exodus 19:14), the priests and the Levites saved themselves (1 Chronicles 15:14), the Father saved the Son (John 10:36), the Son saved Himself (John 17:19) and many other things that do not line up with scripture.

In verse 39, the writer of Hebrews sets up the CONTRAST that makes it clear to me that he was referring to make believers/nominal Christians, not saved people: But WE are not of those who draw back to perdition, but OF THOSE who believe to the saving of the soul. Those who draw back to perdition do not believe to the saving of the soul and those who believe to the saving of the soul do not draw back to perdition.

So after considering the CONTEXT, it seems most likely that "he was sanctified" should be understood in the sense of someone who had been "set apart" or identified as a professing believer in the Hebrew community of believers, but later renounces his identification with other believers, by rejecting the "knowledge of the truth" that he had received, and trampling under foot the work and the person of Christ himself. This gives evidence that his identification with the Hebrew community of believers was only superficial and that he was not a genuine believer.

They forget Jesus died for sins 2000 years ago

If they are not forgiven as promised the moment we receive out gift

They will Never be forgiven. Christ must have forgot to pay for those sins

 

[Eternally Grateful]

This is your response to Jesus words?

No it’s my response to your words

And how you used them

The fact you could not tell me the works we need to be saved shows you do not even understand what you are trying to proclaim

 

[Muna]

No it’s my response to your words

And how you used them

The fact you could not tell me the works we need to be saved shows you do not even understand what you are trying to proclaim

Which words exactly, and how did I used them?

You got totally triggered by my rehilighting his words, why?

 

[Muna]

Matthew 7:24-Therefore whoever hears these sayings of Mine, and does them, I will liken him to a wise man who built his house on the rock: 25 and the rain descended, the floods came, and the winds blew and beat on that house; and it did not fall, for it was founded on the rock.

And you know, if you rehilight that verse this way

Matthew 7:24 Therefore whoever hears these sayings of Mine, and does them, I will liken him to a wise man who built his house on the rock: 25 and the rain descended, the floods came, and the winds blew and beat on that house; and it did not fall, for it was founded on the rock.

Being founded on the rock includes more than just the hearing of his words but the doing of them there

 

[Muna]

And you know, if you rehilight that verse this way

Matthew 7:24 Therefore whoever hears these sayings of Mine, and does them, I will liken him to a wise man who built his house on the rock: 25 and the rain descended, the floods came, and the winds blew and beat on that house; and it did not fall, for it was founded on the rock.

Being founded on the rock includes more than just the hearing of his words but the doing of them there

Contrast between them

Luke 6:49 But he that heareth, and doeth not, is like a man that without a foundation built an house upon the earth; against which the stream did beat vehemently, and immediately it fell;
and the ruin of that house was great.

 

[Eternally Grateful]

Which words exactly, and how did I used them?

You got totally triggered by my rehilighting his words, why?

Lol

Yeah you don’t get it. It’s ok. Follow the conversation

Good day

 

[Eternally Grateful]

Being founded on the rock includes more than just the hearing of his words but the doing of them there

So what does it include what works and why do we work

You do realize I am arguing against a works based gospel. And you planted these words right in the middle of that conversation

So do you believe we must work to stay saved or get saved

Or because we are saved and have true faith?

 

[Muna]

Lol

Yeah you don’t get it. It’s ok. Follow the conversation

Good day

You had asked me the questions on Jesus own words (rehighlighted) not me you.
The only conversation I cannot follow is the one you are starting with me on them.

 

[Muna]

Now you want to talk again?

You are arguing with Jesus words, his words totally triggered you, you have been beside yourself by me rehilighting them. All your questions are because of His words not mine.

 

[Eternally Grateful]

You had asked me the questions on Jesus own words (rehighlighted) not me you.
The only conversation I cannot follow is the one you are starting with me on them.

I asked you a question from the words

You did not or could not answer.

Don”t blame me

 

[Grailhunter]

The doctrine of Once Saved, Always Saved (OSAS) is one of the most misunderstood and misrepresented teachings in the Christian faith. Critics often claim that it encourages sin, ignores repentance, or contradicts church tradition. Some even call it "Gnostic" or "cheap grace."

But OSAS is not a modern invention, nor is it a license to sin. It is a profound expression of the depth of God’s grace, the security of Christ’s finished work, and the freedom of the believer in the New Covenant.

Let’s take a closer look.


---

1. The Biblical Foundation for Eternal Security

The clearest testimony comes from Christ Himself:

> “I give them eternal life, and they shall never perish; no one will snatch them out of my hand.”
— John 10:28



Notice the words: eternal, never, no one. Not even you can snatch yourself from His hand. That’s security, not presumption.

> “Truly, truly, I say to you, whoever hears my word and believes Him who sent me has eternal life. He does not come into judgment, but has passed from death to life.”
— John 5:24



He has eternal life. Not "might have." Not "as long as he behaves." The transfer from death to life is permanent.

> “For by grace you have been saved through faith, and this is not your own doing; it is the gift of God—not a result of works, so that no one may boast.”
— Ephesians 2:8–9



If salvation is not from works, how could it be lost by works?


---

2. Is Grace Conditional? Then It’s Not Grace.

If our salvation depends on maintaining obedience, then the Gospel becomes a contract, not a gift.
You’d be back under law: perform or perish.

That’s not Good News.

The Apostle Paul was clear:

> “Having begun by the Spirit, are you now being perfected by the flesh?”
— Galatians 3:3



You didn’t earn it. You can’t keep it by effort. The same God who saved you is the one who keeps you.


---

3. But What About Apostasy?

What about those who “fall away”? Scripture gives two answers:

1. They were never truly born again



> “They went out from us, but they were not of us…” (1 John 2:19)
Outward faith can mimic real regeneration. Only God sees the heart.



2. God disciplines His children, not disowns them



> “The Lord disciplines those he loves…” (Hebrews 12:6)
Falling into sin invites correction, not rejection.




---

4. OSAS Is Not an Excuse to Sin

True believers don’t want to abuse grace. Why?

> “No one born of God makes a practice of sinning, for God’s seed abides in him.”
— 1 John 3:9



A new heart means new desires.
A Christian may stumble, but he no longer walks in the same direction.


---

5. Historical and Theological Witnesses

Luther: Salvation by grace alone, through faith alone.

Calvin: The elect will persevere because God preserves them.

The Catholic Church, even with its emphasis on mortal sin, still teaches that God’s mercy is greater than human failure.


The early Church saw salvation as a secure covenant, not a fragile agreement.


---

6. Without OSAS, God Becomes a Tyrant

Let’s be honest: If God saves you, but lets go of you the moment you mess up, that’s not a loving Father—that’s a judge with a short fuse.

If salvation can be lost, we live in fear, not faith.

> “There is no fear in love. But perfect love drives out fear…”
— 1 John 4:18



OSAS doesn’t make God weak. It shows He is strong enough to carry us, even when we fall.


---

7. The Cross Is Enough

Jesus doesn’t need to die again every time you sin. He died once for all.

> “For by one sacrifice he has made perfect forever those who are being made holy.”
— Hebrews 10:14



Your justification is not in progress. It is finished.


---

Conclusion

Without OSAS, the Gospel becomes fear-based religion.
With OSAS, it becomes what it was always meant to be: Good News.

God is not calling you to walk a tightrope. He is calling you to trust in a finished work.

Once saved, always saved – not because we hold on to God, but because He holds on to us.

> “If we are faithless, He remains faithful – for He cannot deny Himself.”
— 2 Timothy 2:13

OSAS is definitely a newer belief. A belief that leads people to Hell.

Non-biblical and early Christian writers did not write of OSAS.

And it definitely does not appear in the Ecumenical Councils.

And not a belief of the “founder of Protestantism”…Martin Luther.

The general concept does not occur until John Calvin.

In the early 20th century, eternal security started to become a defining doctrine of the Southern Baptist traditionalism. Around the same period, it also became part of the Plymouth Brethren
theology. Those two forms represents its predominant forms today. In the 1980s, the Free Grace movement voiced this doctrine independently of the notion of personal perseverance, with subsequent variations emerging such as the "Hyper-Grace" teaching.

What the Bible says…..
2nd Corinthians :5:10: For we must all appear before the judgment seat of Christ, that each one may be recompensed for his deeds in the body, according to what he has done, whether good or bad..

Matthew 18:9 And if your eye causes you to sin, pluck it out and cast it from you. It is better for you to enter into life with one eye, rather than having two eyes, to be cast into hell fire.

So then, my beloved, just as you have always obeyed, not as in my presence only, but now much more in my absence, work out your salvation with fear and trembling; Philippians 2:12

1st Corinthians 6:9-10 “Or do you not know that the unrighteous will not inherit the kingdom of God? Do not be deceived; neither the sexually immoral, nor idolaters, nor adulterers, nor homosexuals, nor thieves, nor the greedy, nor those habitually drunk, nor verbal abusers, nor swindlers, will inherit the kingdom of God”

Galatians 5:19-21 Now the deeds of the flesh are evident, which are: sexual immorality, impurity, indecent behavior, idolatry, witchcraft, hostilities, strife, jealousy, outbursts of anger, selfish ambition, dissensions, factions, envy, drunkenness, carousing, and things like these, of which I forewarn you, just as I have forewarned you, that those who practice such things will not inherit the kingdom of God.

1st John 1:9 If we confess our sins, He is faithful and righteous to forgive us our sins and to cleanse us from all unrighteousness.

 

[Eternally Grateful]

Now you want to talk again?

You are arguing with Jesus words, his words totally triggered you, you have been beside yourself by me rehilighting them. All your questions are because of His words not mine.

No. His words did not trigger me

The context of which you shared those words triggered me to ask you a question to try to see how you understand those words

And you have argued every step

But I see you are still hiding again you have failed to answer my question. Again (a different question)

What are you hiding from?

Do you believe we work because we are saved

Or in order to get saved stay saved or keep from losing salvation

I am trying to see where you are comming from

Yep your right Gods promises and us trusting him leads us straight to hell

Smh

 

[Muna]

No. His words did not trigger me

They did, look at how you are behaving

The context of which you shared those words triggered me to ask you a question to try to see how you understand those words

Which context was that exactly? Please provide it for us

And you have argued every step

Where is my argument, please provide it for us

Its you, who have tagged my post and are trying to argue with me, anyone can go back and read your posts tagging mine over and over again.

But I see you are still hiding again you have failed to answer my question. Again (a different question)

How it is that I am hiding in your eyes?

Just because I have failed to answer your questions?

I cannot even figure out what your question is concerning Jesus own words. Not to mention I did not post it, I simply rehilighted it and you been triggered since and been chasing me around trying to get an answer for the highlights that are triggering you.

What stood out in the verse that would make you so insistant I answer to you for it?

What are you hiding from?

I am not hiding, I am watching your reaction to Jesus words rehilighted

Do you believe we work because we are saved

You question (I am supposing) is that you believe Jesus stating, to build upon the rock (includes both hearing his words and doing them) is a saved by works thing in your mind, and so you believe that we should just hear Jesus words and not do them.

Or in order to get saved stay saved or keep from losing salvation

You have some issue with mens doctrines that have nothing to do with the verse I highlighted.

I am trying to see where you are comming from

I know, I prefer to reason from out of the scripture not from someone elses head and how they might link ideas outside of the scriptures.

 

[Muna]

I asked you a question from the words

No you did not, you added all your own words into the question that are not in the text

You did not or could not answer.

You are asking a question using words not found in Jesus words and in that way trying to twist them so that you can argue for mens doctrine

Don”t blame me

I don't blame you for being ignorant.

Yawn

 

[Eternally Grateful]

No you did not, you added all your own words into the question that are not in the text

Whatever

You are asking a question using words not found in Jesus words and in that way trying to twist them so that you can argue for mens doctrine

I don't blame you for being ignorant.

So I will assume your a legalist who thinks we must work to get saved stay saved or keep from losing salvation

And that’s why your hiding

 

[mailmandan]

So what does it include what works and why do we work

You do realize I am arguing against a works based gospel. And you planted these words right in the middle of that conversation

So do you believe we must work to stay saved or get saved

Or because we are saved and have true faith?

Those who promote works righteousness will typically confuse 'descriptive' passages of scripture with 'prescriptive' passages of scripture and the end result is salvation by works.

In Matthew 7:24-26, we find two different foundations with two different results, and not salvation by works, as some would suppose. Each house has a different material upon which its foundation is laid, and each house has a different final outcome. One house is built by a wise man upon a rock, and it stands. The other is built by a foolish man upon the sand, and it collapses.

The rock the wise man builds upon is true righteousness found in Jesus Christ alone. (descriptive of genuine Christians)
The sand the foolish man builds upon is self-righteousness. (descriptive of pseudo-Christians) Only those who truly believe in Him (demonstrative evidence) are wise and hear the words of Jesus and properly act on them.

In context, Jesus mentions false prophets in vs. 15 and He never knew these many people in vs. 23 which means they were never saved. True and false Christians are being contrasted throughout Matthew 7:15-27.

 

[Muna]

Whatever

So I will assume your a legalist who thinks we must work to get saved stay saved or keep from losing salvation

And that’s why your hiding

You can assume whatever you want of me for rehighlighting the Lord own words as I assuredly did.

You have a problem with me doing that, and the questions you have concerning Jesus words are yours before the Lord, something struck you, and it certainly wasn't me. Its also a little strange to keep accusing me of hiding each time I answer you.
