Explaining 1 John 3:6 and 1 John 3:9:
Modern Translations will say practice sin or continue in sin in 1 John 3:9 (as if to say it is talking
exclusively of practicing sin), but this is not the case in the trusted KJV (that existed hundreds of years long before the Modern Translations showed up). (Note: I am not denying that it can be in reference to habitual sin, but it is not exclusively referring to habitual sin but also singular or temporary sin, too.).
The key to understanding 1 John 3:9 is realizing that this "
does not commit sin" is in context to the gnostic belief who think sin does not exist or that sin is an illusion in some way (See 1 John 1:8 and 1 John 2:26). Christian Scientists today think sin is an illusion. OSAS proponents think future sin is forgiven them. So while they believe sin may exist on a physical level, they do not think sin exists for them on a spiritual level because they believe Jesus paid for their future sins (When the Bible never says future sin is forgiven us). In other words, it is those who justify sin in some way who have not been born again spiritually and who have never seen or known Christ and He (the seed) does not abide in them. 1 John 3:6 and 1 John 3:9 is talking about "willful sin" in Hebrews 10:26 in view or light of 1 John 1:8.
In other words,
1 John 3:6, and
1 John 3:9 is in view of "willful sin" or "justifying sin" in some way.
1 John 3:9 should read like this:
"Whosoever is born of God doth not commit sin [willfully, as if to justify it]; for his seed remaineth in him: and he cannot sin [willfully], because he is born of God."
1 John 3:6 should read like this:
"Whosoever abideth in him sinneth not [willfully, seeking to justify their sin]: whosoever sinneth [as if to justify their sin] hath not seen him, neither known him."
This would be in view or light of applying the context of the false gnostic belief that John warned the brethren about in 1 John 1:8.
