I've often stated the difference in the Ten Commandments, and the NT commandments (the law of the Spirit) is "Thou shalt not" vs. "Thou shalt love"
When we don't follow the Spirit and sin, He is still there with conviction, and it is up to us to repent and begin to follow after the Spirit only again.
I do not believe in OSAS, but I would say that is up to us. God chastises His children to turn back as it is not his will that any be lost. But if we don't turn back, well...
36 "For you have need of endurance, so that after you have done the will of God, you may receive the promise:
37 “For yet a little while,
And He who is coming will come and will not tarry.
38 Now the just shall live by faith;
But if anyone draws back,
My soul has no pleasure in him.”
39 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 all the way back to "perdition" and will no longer walk after the Spirit, are doomed. They made their choice.
Let's look at the point you raised. If we don't repent when we commit what we term wilfull sin we are doomed.
Absolutely. I agree with you 100 percent.
But let's look at the practical outworking of the covenant we are under in regards to this. I'm speaking of truly born again Christians. NOT people who's christianity consists of turning up at church once a week, relying on rite, ritual and ceremony to enter heaven, plus not getting Drunk, using foul language, having extra marital affairs, nor smoking. Many believe if they adhere to the above they basically have a free pass to enter heaven. I'm sure you disagree with that view, as I do.
OK. The law is written in the mind and placed on the heart of the truly born again believer. We agree on that.
What happens when you wilfully go against what is in your heart? What is the inevitable outcome of that?
Your conscience is going to be seered isn't it. You will have no rest, no peace until you sort out what you did wrong. If you transgressed the law in your heart by being unkind to someone, you must go and apologise to them in order to have your peace back.
The truly born again believer loves God. They cannot hide from how he desires them to live, and avoid what he does not want them to do, for the law is in their mind . And in their heart they want to obey him, for that is where his good and holy laws have been placed.
When a born again Christian does wilfully transgress that law( for only Christ was sinless when he walked this earth) their conscience will be seered for they have offended the one they love, and gone against what is in their heart.
They will have no rest and no peace until they kneel before their Father in heaven and tell him they are sorry for erring. Then, and only then will they get their peace back.
As surely as night follows day, the true Christian will repent/ say sorry to their heavenly Father when they err. The burden in them until they do so would be too great.
Anyone who could continue to sin, untroubled, and did not come and say sorry to God when they erred could not love him or have his laws in their hearts.
So repentance is part of the true Christians walk. They will always repent/ say sorry. They wouldn't need anyone to tell them they must for the Spirit dwells in them.
Those who don't repent cannot have the law in their hearts, and only these people have a saviour from their sin.
So practically speaking, all true Christians will always repent. I don't see it as a work to ensure salvation. Just something you will naturally do. The same as you will inevitably say sorry to anyone you love in your heart whom you at anytime offend
