As you can see, John did not mean to say that the born-again person is utterly sinlessly perfect. Such an idea flies in the face of other parts of Scripture that directly contradict such a statement. See above. What's more, John himself confounds such a reading of his own words:
1 John 1:8-10
8 If we say we have no sin, we deceive ourselves, and the truth is not in us.
9 If we confess our sins, he is faithful and just to forgive us our sins and to cleanse us from all unrighteousness.
10 If we say we have not sinned, we make him a liar, and his word is not in us.
1 John 2:1
1 My little children, I am writing these things to you so that you may not sin. But if anyone does sin, we have an advocate with the Father, Jesus Christ the righteous.
In both selections from John's own letter, he includes himself in his remarks - "we," "us," "our" - identifying with his readers as one of them and applying his words to himself, as well as to them. Was John writing as an unsaved sinner, then? He indicated that he was, like his readers, unable to say he was without sin and he stated also that "we" who may sin - both John and his readers - have an Advocate with the Father, Jesus Christ. Only if you're going to assert that John was not saved can you continue to hold that he thought every truly born-again person was sinlessly perfect. His testimony about himself was that he was both a sinner and that, like others who sinned, he had an Advocate, too, in Jesus.
Scripture has sin as unbelief, and righteousness as belief.
Who said both can be done, maybe modern translations, but in practice, Christ is without sin ( He is faith/the love of God, and the devil is hatred, murder, no faith, no righteousness.
Does this sound familiar to anyone ? That only because of the words, we and our, this means the apostles of the Lord are included with sinners ? ( what happened to casting out from the church, the wicked person who does sins, and calls themselves a believer, if all are sinners?) This is all too familiar to label the Corinthians as born again, only for the sake of a word, a name, that they are called Christians, or babes in Christ, go to a church, are the building of God, a human body, and yet all in the world are these same, they all consider they are Christians, but many are called and few are chosen, is wisdom not justified of her children, and the unjust have no shame or sense of justice/the righteous jusgement of God, to render to every man according to his ways. ( the ways should be in Christ as we see in apostle Paul.)
The apostles show difference between them and the ones who have not heard, as they had true fellowship with the Father and with HIs Son Jesus Christ.
1 John 1:3 That which we have seen and heard declare we unto you, that ye also may have fellowship with us: and truly our fellowship is with the Father, and with his Son Jesus Christ.
The apostles are different not only to unbelievers, they are the true example to the believers also.
Paul speaks to the Corinthians as unto children, but that does not mean born again, it means appealing to them to follow/believe correctly.
Just like John ( it has to be the very same) the fellowship is that believers cannot be yoked with unrighteousness. They are CLANSED FROM ALL UNRIGHTEOUSNESS.
Paul continues to the same Corinthians, that the temple of God. ( they who defile the temple of Gd are destroyed. 1 Corinthians 3:17.) has no agreement with idols, and they are the temple God walks in, and for this, THEY ARE TO COME OUT FROM AMONG THEM AND TO BE SEPERATE. ( from sinners/ as the High priest who BECAME US.) to not touch wat is unclean. ( CLEANSED FROM ALL UNRIGHTEOSNESS.) and He will receive us, ( then our fellowship truly is with the apostles as theirs was WITH THE FATHER AND WITH HIS SON JESUS CHRIST.) and be a Father unto jus, we shall be HIs sons and daughters.....
1 John 1:9 If we confess our sins, he is faithful and just to forgive us our sins, and to cleanse us from all unrighteousness.
2 Corinthians 6:13 Now for a recompence in the same, (I speak as unto my children,) be ye also enlarged.
14 Be ye not unequally yoked together with unbelievers: for what fellowship hath righteousness with unrighteousness? and what communion hath light with darkness?
15 And what concord hath Christ with Belial? or what part hath he that believeth with an infidel?
16 And what agreement hath the temple of God with idols? for ye are the temple of the living God; as God hath said, I will dwell in them, and walk in them; and I will be their God, and they shall be my people.
17 Wherefore come out from among them, and be ye separate, saith the Lord, and touch not the unclean thing; and I will receive you.
18 And will be a Father unto you, and ye shall be my sons and daughters, saith the Lord Almighty.
Hebrews 7:26 For such an high priest became us, who is holy, harmless, undefiled,
separate from
sinners, and made higher than the heavens;
We have that advocate with the Father, we have to sin not. ( believe in Him/be separate from sinners, touch not the unclean thing, have true fellowship with the Father and Son, then He receives us to be a Father unto us.)
So to know the Father, to walk as the Son walked, ( not some idea that the apostles say us, our, and they are sinners) we are directed how, keeping His words, with the truth no lie, with love no hatred in what we do to others, because if we keep the word of God, the love of God is perfected in them, ( before the hatred of the devil was in them) and that is how they know they are in God, ( no longer in the devil)...
1 John 2:1 My little children, these things write I unto you, that ye sin not. And if any man sin, we have an advocate with the Father, Jesus Christ the righteous:
1 John 2:3 And hereby we do know that we know him, if we keep his commandments.
4 He that saith, I know him, and keepeth not his commandments, is a liar, and the truth is not in him.
5 But whoso keepeth his word, in him verily is the love of God perfected: hereby know we that we are in him.
6 He that saith he abideth in him ought himself also so to walk, even as he walked.
