That is what I glean from the scriptures overall. Especially Romans 4, and balancing that out with other scriptures like where it says if we keep on willfully sinning there is no more sacrifice for sins, and where it says the unrighteous will not inherit the kingdom of God. James acknowledged that "we offend in many ways all". John said if we say we have no sin we lie. I have the impression that the Lord graciously longsuffers our inadvertent missteps and foibles in our immaturity along the way, as long as we are penitent and seeking to do better. Otherwise grace isn't grace. (That is different from someone who is continually sinning knowingly and deliberately without remorse...that makes a mockery of salvation, and signifies a seared conscience and falling away.) But we all err inadvertently in ways that we aren't even aware of until/unless the Lord reveals it to us. It is why we are told to bear with one another....in other words extend the same grace to others that we ourselves are receiving from the Lord......our foibles are usually apparent to others long before we become aware of them. The Lord's supper is even provision and opportunity to examine ourselves and bring anything to the cross that we find we need to. Grace is grace and it is given to us because we need it, not because we don't. As long as we don't abuse that grace by using it a license to sin deliberately and wilfully, because God is not mocked.
Sorry for the delay, which was mainly due to connection problems but also my brain was not quite online and had decided to take a day off :)
Of course, wilful sin is not acceptable and we are in a state of backsliding or even apostacy in that case. Inadvertent mishaps as you call them, are what separates the two schools of holiness theology, as we have been discussing regarding Keswick theology v early church teaching which has made an appearance at times throughout church history in the west.
I have had the feeling a few times that epi has been very much influenced by it but it has been hard for me to get him to name his sources of influence. So I wonder if you have likewise gathered that influence too.
I get that idea when he talks about there being 'three paths' ie the unsaved, the believers walking in the Spirit, and those still walking in the flesh, or carnal though known as 'righteous' according to him and includes even the non religious too which has caused confusion here. I guess saying that their intentions are good which is roughly what you said. Is that correct?
But this is what Paul is preaching in Romans 7, when he recollects his own experience of his attempts to overcome these 'mishaps' despite his struggles '18 For I know that in me (that is, in my flesh,) dwelleth no good thing: for to will is present with me; but how to perform that which is good I find not.
His intentions were good '22 For I delight in the law of God after the inward man:
23 But I see another law in my members, warring against the law of my mind, and bringing me into captivity to the law of sin which is in my members.
So the text is about the situation whereby he is under conviction that these inadvertent sins are not acceptable to God, and why should they be when God has the power to deliver us to be what we once were (the state of Adam before he sinned or in his case innocent in preparation for perfection from eating from the tree of life).
Here is a quote from an orthodox source. I know you don't like the word theosis but it is only the Greek for the ultimate state we are discussing which can easily be replaced by entire sanctification for us westerners.
'PARTAKERS OF DIVINITY: THE ORTHODOX DOCTRINE OF THEOSIS
Transfiguration of our nature from image to likeness we are deified, according to the words of the psalmist (Ps 82:6).65 Salvation, then, "is not possible but by the deification of the saved," writes Dionysius, and "deification is likeness and union with God."66 Irenaeus sums up the dilemma of humanity and the remedy of the incarnation as the deification of people through the movement from image to likeness: The Word of God was made man, assimilating Himself into man, and man into Himself, so that by means of his resemblance to the Son, man might become precious to the Father. For all times long past, it was said that man was created after the image of God, but it was not actually shown; for the Word was as yet invisible, after whose image man was created. Wherefore also he did lose the similitude. When, however, the Word of God became flesh, He confirmed both of these: for He showed forth the image truly, since He became Himself what was His image; and He re-established the similitude after a sure manner, by assimilating man to the invisible Father by means of the visible Word.67 In this assimilation to God, people move from nature to grace, from the divine image to the divine likeness, from sin to salvation through deification.' (JETS 37/3 (September 1994) 365-379 PARTAKERS OF DIVINITY: THE ORTHODOX DOCTRINE OF THEOSIS DANIEL B. CLENDENIN)
There is a process on getting there and it involves what you talked about that is, sinning unintentionally and coming for forgiveness, but that stage is for our carnal times and not for walking in the Spirit.
What of the carnal ones? Well I believe that they are under God's wrath because everything in scripture is simple and not mixed, so good and evil, spirit and flesh, sinner and saint etc. How God deals with those who are striving but unable to enter in, I can only say I do not know.
Jonathan Edwards brought his church into revival after preaching the well known sermon 'Sinners in the hands of an angry God' and said that they are hanging over the gates of hell by a thread. Today is the day of salvation when we hear the full gospel.
I must add that Dr Andrew Murray shows his theology to be unbalanced here and not in accordance with early teaching, though he has led many on to the pathway to holiness.
