If we say we have no sin, we deceive ourselves.

Yes, if we say we have no sin for Christ to take away…

BUT:

“If we confess our sins, he is faithful and just to forgive us our sins, and to cleanse us from all unrighteousness.” (1Jn 1:9, KJV)

And so, the natural progression of the believer leads him to a life of righteousness, because:

“We know that whosoever is born of God sinneth not; but he that is begotten of God keepeth himself, and that wicked one toucheth him not.” (1Jn 5:18, KJV)

Think about that!

Whenever you sin, the wicked one is touching you!

REPENT!

You too @mailmandan

And you got the reason.

If Christ takes your sins away, how are there any left?

And you ignore John’s writings later in the letter!

Because you want to keep your comfort in your occasional indulgence in sin (as it seems).

You don’t seem to want to exercise yourself in holiness for some reason.

I departed from evil, and yet you, you don’t even seem to realize how your behavior is unbiblical.

I’m your prey simply because I preach the truth:

“Yea, truth faileth; and he that departeth from evil maketh himself a prey: and the LORD saw it, and it displeased him that there was no judgment.” (Isa 59:15, KJV)
Christ does take away the sins of believers (Acts 10:43; 13:38-39; 15:7-9 etc..) yet that still does not mean we will never sin again at all. (1 John 1:8-10; 2:1) I never said anything about finding comfort in occasional sins, which is bearing false witness against me (slander) and that is sin. So much for you reaching sinless perfection!

You claim that you have no sin, and according to John, you deceive yourself and the truth is not in you. Suffering from a terminal case of self righteousness and bearing false witness against me is not departing from evil. It's remaining in evil and in unbelief.

We’ll, sure.

We all have free will to force our new man into sin again, if we choose. But we are warned against this in serious terms here:

“… if we sin wilfully after that we have received the knowledge of the truth, there remaineth no more sacrifice for sins, But a certain fearful looking for of judgment and fiery indignation, which shall devour the adversaries.” (Heb 10:26-27, KJV)

In regard to Hebrews 10:26, to "sin willfully" here 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 willful, continuous 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)

According to 1 John 1:8 you need to REPENT!

Once again, your pride and ego prevents you from fearing this passage; fear, which would produce a contrite and humble spirit in you.

Instead, you view the scripture with an intellectual mind… not a humble mind.

This lie is so obvious that it’s mind boggling how you have convinced yourself so thoroughly of this lie. But, the flesh is a powerful thing that blinds people.

The people in this passage have not rejected Christ you liar! Read the text:

“Of how much sorer punishment, suppose ye, shall he be thought worthy, who hath trodden under foot the Son of God, and hath counted the blood of the covenant, wherewith he was sanctified, an unholy thing, and hath done despite unto the Spirit of grace?” (Heb 10:29, KJV)

The “we” mentioned here were sanctified by the blood! (Unbelievers CANNOT be sanctified!)

“For if we sin wilfully after that we have received the knowledge of the truth, there remaineth no more sacrifice for sins” (Heb 10:26, KJV)

There you go judging me again. Neither practicing sin and rejecting Christ deliberately (Hebrews 10:26) nor suffering from a terminal case of self-righteousness (1 John 1:8) comes from a contrite and humble spirit.

Pride and ego would claim sinless perfection. (1 John 1:8-10) In context, we discover that those who willfully sin by rejecting Christ, deliberately, draw back to perdition, and do not believe to the saving of the soul. (Hebrews 10:39)

“For if we sin wilfully after that we have received the knowledge of the truth, there remaineth no more sacrifice for sins” (Heb 10:26, KJV)
Your pride and ego is on full display by calling me a liar! Now if the word 'sanctified' in Hebrews 10:29 is used to describe saved people who lost their salvation, 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 and 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 underfoot 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 this community of Hebrew believers, but later renounces his identification with other believers, by rejecting the "knowledge of the truth" that he had received and trampling underfoot the work and the person of Christ himself. This gives evidence that his identification with these Hebrew believers was only superficial and that he was not a genuine believer.

He does not have faith in God.

He is not confident that he who began will complete it (it is an ongoing process)

he is not assured that by one offering he perfected people in process of being sanctified (again an ongoing process)

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


Whoever hates his brother is a murderer, and you know that no murderer has eternal life abiding in him.
1 John 3:15


his brother” refers to two brothers in Christ.


Born again Christians who begin to hate their brother for whatever reason, do not have eternal life remaining in them.

so we are saved by doing the work of not hating our brother.

got it..

I guess I can boast of not hating my brother.. so i am a child of God..

But, the flesh is a powerful thing that blinds people.

The people in this passage have not rejected Christ you liar! Read the text:
2 Corinthians 4:3 - But if our gospel be hid, it is hid to them that are lost: 4 In whom the god of this world hath blinded the minds of them which believe not. lest the light of the glorious gospel of Christ, who is the image of God, should shine unto them.

That is a very heart of the reason why folks are blind and do not believe the gospel.

By calling me a liar, you are bearing false witness, which is sin. So much for sinless perection! In what universe is drawing back to perdition and not believing to the saving of the soul, (Hebrews 10:39) not rejecting Christ?

In other words, "type 2 works salvation" or salvation by works at the back door. That's faith in SELF.

"sanctified" (which is the verb form of the adjective "holy") which means "set apart," and doesn't necessarily refer to salvation.

Now you’ve stumbled into another error with your long winded, scholastic, word salad.

A person who has never genuinely believed the gospel, who hasn’t gotten saved, still has the sacrifice of Christ as means of salvation upon genuinely believing. He still has the sacrifice of Christ available to him! (since he was that “nominal” Christian you love to bring up).

It is those who were saved (sanctified by the blood - “we”) who have no other sacrifice for sin!

“For if we sin wilfully after that we have received the knowledge of the truth, there remaineth no more sacrifice for sins…” (Heb 10:26, KJV)

I properly harmonized scripture with scripture before reaching my conclusion on doctrine. You just do not understand and there is a reason for that.

@mailmandan didn’t have an answer for what I just posted to him.

Please explain how a fake Christian has no more sacrifice for sins when he never believed the gospel in the first place.

No doubt many folks come to believe in the gospel later in years after rejecting it at first.

Once a true and genuine belief has been expressed to God, then the danger of having no more sacrifice for sins comes into play if that believer returns to sin.
