First of all, your opinion on the meaning of verses referring to being born of God means little because you cannot even understand that a person is born of God by faith and faith alone despite what we read here:
"He came to that which was his own, but his own did not receive him. Yet to all who did receive him, to those who believed in his name, he gave the right to become children of God—children born not of natural descent, nor of human decision or a husband’s will, but born of God" (Jn.1:11-13).
The Jews who lived under the law were born again when they "believed" that the Lord Jesus is the Christ:
"Everyone who believes that Jesus is the Christ is born of God, and everyone who loves the father loves his child as well" (1 Jn.5:1).
Of course John and the people he addressed in his first epistle all believed that the Lord Jesus is the Christ so they were all born again. And here is what he said about himself and those to whom he addressed his words:
"If we confess our sins, he is faithful and just and will forgive us our sins and purify us from all unrighteousness" (1 Jn.1:9).
John sure didn't think that he had not sinned since he became born of God or else he wouldn't have said told the believers as well as himself are to confess their sins.
What John is saying at 1 John 3:9 is that anyone is born of God does not sin because God's seed remains in him. God's seed is his nature and therefore the child partakes of the nature of his Parent. Any sin which a person who is born of God commits does not stem from the believer's regenerate nature. And that explains why Paul said the following:
"For the good that I would I do not: but the evil which I would not, that I do. Now if I do that I would not, it is no more I that do it, but sin that dwelleth in me" (Ro.7:19-20).
Of course this explanation is way above your head because you still have not learned that being born of God is a result of faith and only faith.
"Everyone who believes that Jesus is the Christ is born of God, and everyone who loves the father loves his child as well" (1 Jn.5:1).
