More hermeneutical nonsense.
John is not writing to unbelievers in grip of the view of their sin.
He is writing to believers, "my little children," whose sin has been forgiven by faith in Jesus Christ.
Believers don't need an advocate with the Father for their past sin, it is all forgiven,
so for what forgiveness is the advocate pleading?
The advocate is going to plead for the forgiveness of new sin after coming to saving faith.
Prove your point from the text instead of throwing wild accusations. context friend context, I used more than one text to make my point.
You assume its new sin but the text does not say that, Is John addressing believers, Yes that is clear. But is it new sins they need help with of sins they come to realize were already in their life but did not see till they came closer to Jesus?
John is clear that the reason He wrote these things is so they "sin not" so John clearly believes that in Jesus we can cease from sin/works of the Devil.
1Jn 2:3 And hereby we do know that we know him, if we keep his commandments.
1Jn 2:4 He that saith, I know him, and keepeth not his commandments, is a liar, and the truth is not in him.
Sin is breaking the commandments, so if those who know Him keep them then they are not sinning, simple. see 1John 3:4 for Johns definition of sin.
1Jn 2:26 These things have I written unto you concerning them that seduce you.
The issue for which John is writing is people seducing the believers and deceiving them as to the truth. what is this deception?
1Jn 3:7 Little children, let no man deceive you: he that doeth righteousness is righteous, even as he is righteous.
1Jn 3:8 He that committeth sin is of the devil; for the devil sinneth from the beginning. For this purpose the Son of God was manifested, that he might destroy the works of the devil.
1Jn 3:9 Whosoever is born of God doth not commit sin; for his seed remaineth in him: and he cannot sin, because he is born of God.
sounds to me like some here are twisting Johns own words.
John is clear that the deception is people saying that you can be righteous and do unrighteous/sinful acts.
People are teaching that the Devil still has power over the believer to cause them to sin. but John says that Christ overcame the Devil and destroyed His works. that those who are born of God continue no more in sin because Christ is in them.
