TF,
Have you considered 1 John 3?
1 John 3:9 (KJV) states: ‘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’. Is that your experience as a born again believer? Have you become sinlessly perfect so you 'do not commit sin'.
The translators of the NIV have tried to convey the meaning of the Greek tenses in this verse,
1 John 3:9 (NIV): ‘No one who is born of God will continue to sin, because God’s seed remains in them; they cannot go on sinning, because they have been born of God’.
1 John 3:6-8 (NIV) gives some context:
6 No one who lives in him keeps on sinning. No one who continues to sin has either seen him or known him.
7 Dear children, do not let anyone lead you astray. The one who does what is right is righteous, just as he is righteous. 8 The one who does what is sinful is of the devil, because the devil has been sinning from the beginning. The reason the Son of God appeared was to destroy the devil’s work.
Therefore, how is it possible for a born again believer to keep on sinning and still enter the kingdom of God? John writes that such a person has neither seen nor known Christ. That person who continues in sin is 'of the devil' and he is one who leads believers astray.
