@Malcolm the Seceder I see I should make a mention 😃

@Derde We must distinguish between justification and sanctification. We are justified by faith alone, and that faith is a gift of God. When we are converted we are regenerated and have the righteousness of Christ imputed to our soul. This new principle has the effect of sanctifying the believer.

James tells us that faith without works is dead and that we show our faith by our works. James 2

Matthew 7:16-20

So a true believer is not depending upon his good works as the basis of his salvation. But true faith will produce good works in the life of the believer

Sanctification is not by works, but by the blood of Christ.
Hebrews 10:14 For by one offering he hath perfected for ever them that are sanctified.
1 Corinthians 1:30 But of him are ye in Christ Jesus, who of God is made unto us wisdom, and righteousness, and sanctification, and redemption:
It's not a special word: it just means "made holy".

Yes. Made holy. What does that mean? It means living in accordance with the standard of holiness which is the law of God. I didn't say we are sanctified by our works. Our works are the fruit of our sanctification

No.

Ditsem! @Derde, you just advanced to level 2!

It means that even where you fail to live in accordance with the holiness that you have in Christ, you are still holy:
1 Peter 1:4 To an inheritance incorruptible, and undefiled, and that fadeth not away, reserved in heaven for you,
The law is the law. It's a thing. The gospel is not the law:
John 1:17 For the law was given by Moses, but grace and truth came by Jesus Christ.

The law is no longer to us a covenant of works because Adam fell and we are no longer able to keep it perfectly. But it does bind us a moral law.

Nobody but Christ has kept the law perfectly.

Exactly

But you say sanctification is keeping the law

But not perfectly. But if you'll read what the Westminster Confession says the believe is made progressively holy but never perfectly

A believer who sins is still saved because he is accepted for Christ's sake, not his own

Then you're guilty of all.
James 2:10 For whosoever shall keep the whole law, and yet offend in one point, he is guilty of all.

But being accepted in Christ means that the believer will be forgiveb

Forgiven

Will be forgiven?

Future tense?

John 5:24 Verily, verily, I say unto you, He that heareth my word, and believeth on him that sent me, hath everlasting life, and shall not come into condemnation; but is passed from death unto life.

Well we're talking about hypothetical sins so yes I'm talking in the future tense

I'm in present tense:
Galatians 3:26 For ye are all the children of God by faith in Christ Jesus.

To be more precise when a sinner is converted all his sins are washed away past present and future but he still needs to ask forgiveness for any sins he goes on to commit

And if he doesn't ask, kinda knows, and doesn't care?

Well if he doesn't repent then he's not saved

So if you die in a sinful rage that you don't repent of, you're going to hell?

Someone who doesn't care that he has sinned and doesn't seek forgiveness is strongly suggesting he's not a true believer

No and that's not what you said

You've never sinned and not cared? Are you a real person?

If it's ultimately that great attitude that determines heaven and hell, then it's the works of the law, and Jesus died for nothing.
Galatians 2:21 I do not frustrate the grace of God: for if righteousness come by the law, then Christ is dead in vain.

Let's take this one point at a time. You mentioned someone who sins, knows it, but doesn't care. Such a person is suggesting by his attitude that he is not saved. A true believer would care that he had sinned. He would be mournful for his sins. He would feel guilty and alienated from God. Yes, he might go for a long time without repenting. This might be for a few reasons: a) his sin hasn't yet been brought fully to his understanding, b) he might love his sin so much that he doesn't want to let it go (believers often have a particular besetting sin), c) he might ask for forgiveness every time he commits a specific sin, but still nurses the underlying sinful desire

But someone who knows full well that he has sinned and is not bothered by it is suggesting that he is no saved. Spiritual life in the soul will always bring guilt for sin committed. That is a fruit of the Spirit indwelling the believer

So every time someone sins, which is generally a failure of the will, you suggest he's not saved.

I don't see "guilt" in the fruit of the Spirit. love, joy, peace, longsuffering, gentleness, goodness, faith, meekness, temperance:

Someone who is in a sinful rage and dies in that moment is very different. It is not required of the believer that he has asked forgiveness of every single sin before he can enter Heaven. That is Roman Catholicism.
