Amen! The NASB says - No one who is born of God "practices" sin (1 John 3:9). The idea of "practice" is to perform repeatedly or habitually and thus describes repetition or continuous action. The present tense describes the practice as habitual, as one's lifestyle or bent of life.
The devil has deceived people in many ways and with many false doctrines, and the heresy of sinless perfection in the flesh is one of them.
1 John 1:8 - "If we say that we have no sin, (PRESENT TENSE) 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 that we have not sinned, (PAST TENSE) we make him a liar, and his word is not in us."
