See what it says in 1 Jn 1:8:
"8 If we claim to be without sin, we deceive ourselves and the truth is not in us. 9 If we confess our sins, he is faithful and just and will forgive us our sins and purify us from all unrighteousness. 10 If we claim we have not sinned, we make him out to be a liar and his word is not in us.
it's impossible to have Fellowship with those in darkness because they are still on The Death Side of The Cross excusing sin. You skip over the beginning of 1 John 1.
1 John 1 is to people that are not in Fellowship so they are walking in darkness ...meaning the ...if we say we don't sin we are a liar ... was Taking about ending their darkness by Fully Repenting. they wanted to say they were in Fellowship without Denying themselves future sins.
The Reborn don’t deliberately sin after Full Repentance …if they want to remain Saved:
This is Talking about Repentance before Rebirth/Adoption (Getting on The Cross with Him once: Romans 6):
[1 John 1:8-10 KJV] If we say that we have no sin, 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, we make him a liar, and his word is not in us.
The Bible didn't have Chapters for a thousand years. Someone evil split 1 John 1 short to make the beginning of 1 John 2 look like a different subject. The SPIRIT, through John, was still Talking about Repentance before getting on The Cross with The Advocate!
That's why The SPIRIT talks about the sins of the whole world.
Here It is continued without a gap:
[1 John 2:1-2 KJV] My little children, these things write I unto you, that ye sin not. And if any man sin ((the world)), we have an advocate with the Father, Jesus Christ the righteous:
2 And he is the propitiation for our sins: and not for ours only, but also for the sins of the whole world.
How does it make any sense for It to be Talking about sins of the whole world at that point in The Scripture ...if they want it to mean the Reborn are Forgiven for new sins?
Repentance for the world (any man) has an Advocate before Rebirth!!!
It's instructions on how to become Reborn (Repentance) which the whole world can do also. It's not Talking about sin after Rebirth at all!
The Advocate is not available on The Cross for The Reborn because they should be New Life on The Other Side of The Cross ...not needing His Blood from The Cross anymore.
[Heb 10:26 KJV] For if we sin wilfully after that we have received the knowledge of the truth, there remaineth no more sacrifice for sins,
So ask this question: Can your future sins be forgiven from The BLOOD of The Advocate on The Cross after you have died with CHRIST and raised to New Life?
