This say it pretty plain;
1Pe 1:23 Being born again, not of corruptible seed, but of incorruptible, by the word of God, which liveth and abideth for ever.
1Jo 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.
1Jo 4:7 Beloved, let us love one another: for love is of God; and every one that loveth is born of God, and knoweth God.
1Jo 5:1 Whosoever believeth that Jesus is the Christ is born of God: and every one that loveth him that begat loveth him also that is begotten of him.
1Jo 5:4 For whatsoever is born of God overcometh the world: and this is the victory that overcometh the world, even our faith.
1Jo 5:18 We know that whosoever is born of God sinneth not; but he that is begotten of God keepeth himself, and that wicked one toucheth him not.
"Born of God", is being Born Again by the Word of God, which liveth and abideth forever; Jesus Christ in you the hope of Glory;
Colossians 1:27-29 To whom God would make known what is the riches of the glory of this mystery among the Gentiles; which is Christ in you, the hope of glory: Whom we preach, warning every man, and teaching every man in all wisdom; that we may present every man perfect in Christ Jesus: Whereunto I also labour, striving according to his working, which worketh in me mightily.
He is our perfection, He is now our life, the life that does not sin, the real "I" is Jesus Christ in me and He cannot sin. So, "It is no longer I who sin but sin that dwelleth in me", That is why the body of flesh (sin) must die and God give us a new body like His Son Jesus Christ.
Our Spirit is alive unto God by the Spirit of Christ in us, our soul/mind is alive unto God and being conformed to the Mind of Christ by the Holy Spirit Teacher.
Ro 7:25 I thank God through Jesus Christ our Lord. So then with the mind I myself serve the law of God; but with the flesh the law of sin.
Ro 15:6 That ye may with one mind and one mouth glorify God, even the Father of our Lord Jesus Christ.
1Co 1:10 Now I beseech you, brethren, by the name of our Lord Jesus Christ, that ye all speak the same thing, and that there be no divisions among you; but that ye be perfectly joined together in the same mind and in the same judgment.
1Co 2:16 For who hath known the mind of the Lord, that he may instruct him? But we have the mind of Christ.
Php 1:27 Only let your conversation be as it becometh the gospel of Christ: that whether I come and see you, or else be absent, I may hear of your affairs, that ye stand fast in one spirit, with one mind striving together for the faith of the gospel;
2Th 2:2 That ye be not soon shaken in mind, or be troubled, neither by spirit, nor by word, nor by letter as from us, as that the day of Christ is at hand.
1Pe 1:13 Wherefore gird up the loins of your mind, be sober, and hope to the end for the grace that is to be brought unto you at the revelation of Jesus Christ;
This is who we are to God; "It is no longer I", "but Christ who lives in me".
Galatians 2:16-21 Knowing that a man is not justified by the works of the law, but by the faith of Jesus Christ, even we have believed in Jesus Christ, that we might be justified by the faith of Christ, and not by the works of the law: for by the works of the law shall no flesh be justified. But if, while we seek to be justified by Christ, we ourselves also are found sinners, is therefore Christ the minister of sin? God forbid. For if I build again the things which I destroyed, I make myself a transgressor. For I through the law am dead to the law, that I might live unto God. I am crucified with Christ: nevertheless I live; ((((((yet not I, but Christ liveth in me:))))) and the life which I now live in the flesh I live by the (((faith of the Son of God,))) who loved me, and gave himself for me. I do not frustrate the grace of God: for if righteousness come by the law, then Christ is dead in vain.
We the Born Again are the son's of God by the Son of God that is in us. "It is no longer I who live, but Christ who lives in me. This is now our lives, we are dead to sin and the old man is dead to God. We are now new creatures in Christ Jesus. 2 Corinthians 5:17 Therefore if any man be in Christ, he is a new creature: old things are passed away; behold, all things are become new.
Galatians 6:15 For in Christ Jesus neither circumcision availeth any thing, nor uncircumcision, but a new creature.
Revelation 3:14 And unto the angel of the church of the Laodiceans write; These things saith the Amen, the faithful and true witness, the beginning of the creation of God;
We are the New Creation of God, Christ Jesus being the first and the head of His Body the Church, which is "His Body".
