You are correct. John does rebuke unrepentant sinners. We agree.
Then you are rebuked.
1 John can, and does, serve another purpose.
To rebuke unrepented believers, that are still condemned with unbelieving sinners.
And specifically sinful belivers that say they are in the light, while walking in darkness.
And also say they have no sin condemned by God.
It is written to believers who still sin from time to time.
Correct. unrepented believers that still walk in darkness, and not in the light with Jesus.
This personal accusation against all believers is false. There is no safety in numbers, especially when made up to justify oneself.
John includes himself as a repentant sinner.
Sinful believers that seek to justify their sinning, do. Along with their other apostle and bad example of being a double hearted worst of sinners.
That which we have seen and heard declare we unto you, that ye also may have fellowship with us: and truly our fellowship is with the Father, and with his Son Jesus Christ.
John speaks of himself walking in the light while writing the words of Christ.
This then is the message which we have heard of him, and declare unto you, that God is light, and in him is no darkness at all. If we say that we have fellowship with him, and walk in darkness, we lie, and do not the truth:
He includes himself in the warning of the Lord against hypocrisy of naming Christ and walking in darkness. The warning also includes the delusional belief, that we are not condemned with the world, if we are ever walking with the world in darkness.
So did Paul in his letters.
That other sinful apostle for self-justifying sinners to follow into more sinning.
But shun profane and vain babblings: for they will increase unto more ungodliness.
That is what makes the Christian life possible for me.
Christian life and religion is not necessarily Christians walking with Jesus with His pure religion.
Same for Jews living in the Jews religion, that rejects Jesus as Lord and God, much less walking with Him.
John and Paul showed me, with their own words, they were sinners saved by grace, through faith in Jesus.
The only sinners saved by grace through faith, are repented saints saved by grace from sinning, through the faith of God.
And she shall bring forth a son, and thou shalt call his name JESUS: for he shall save his people from their sins.
Sinners saved by grace while sinning, is through their own faith and grace.
For by grace are ye saved through faith; and that not of yourselves: it is the gift of God:
That faith of Jesus that saves us from sinning, is not our own from ourselves, but it is the gift of God to them that repent of their sinning for Jesus's sake.
Therefore leaving the principles of the doctrine of Christ, let us go on unto perfection; not laying again the foundation of repentance from dead works, and of faith toward God,
If anyone is following a sinful apostle into the worst of sinning, then they are become just like him.
If anyone makes an apostle to be the worst of sinners, then their apostle is made just like them.
Downgrading sin against God to a mistake, is the dumbing down of the gospel of God into a sinful relgion.
I repent every day before I rest. I want to keep my relationship with God as pure as I can.
Saying we're sorry at the end of every sinful day for the day's sinning, is not repenting of the sinning.
Let the wicked forsake his way, and the unrighteous man his thoughts: and let him return unto the LORD, and he will have mercy upon him; and to our God, for he will abundantly pardon.
God's repentance is of thoughts and works, not just thoughts alone.
For godly sorrow worketh repentance unto salvation not to be repented of: but the sorrow of the world worketh death.
The sorriness of the world for doing evil, without repenting of the evil, still works the death of sinning.
Those who believe in sinning, sin. It's their faith.
I don't need any forgiveness for not sinning, neither ask for it.
I have not repented of doing righteousness.
For godly sorrow worketh repentance unto salvation not to be repented of:
I am not going to pick apart your words.
Those who have no words to correct, can either agree and do them, or ignore them and do their own thing anyway.
You may pick mine apart all you like.
I only rebuke words corrupting the words of God, by the words of God.
Isn't it interesting that when we forgive others we forgive ourselves?
Human social psychology is not the truth of God.
God does not forgive Himself, if He forgives others. Not do the righteous and innocent, that have done no
