I am not going to address all your misunderstandings of Scripture
Beginning your opening statement with a preconceived (psychology tactic) is a fail.
So I am going to simply deal with one of my favorite verses that you have misinterpreted. 1 John 1:9. You say this is dealing with when we are first saved. It’s odd.
1 John 1:9 is in context to 1 John 2:1 where John says for us to “sin not” but if we do by some chance we have an advocate that we can go to named Jesus Christ.
1 John 1:
[
9] If we confess our sins, he is faithful and just to forgive us our sins, and to cleanse from all unrighteousness.
1 John 2:
[
1] My little children, these things write I unto you, that ye sin not. And if any man sin, we have an advocate with the Father, Jesus Christ the righteous:
1 John 1:9.........
APPLIES to one who is a: BELIEVER, Jesus IS the Christ, Son of God,
And believes he has Sinned or is continuing to Sin. IF he continues BELIEVING, continues to sin, he CONTINUES to HAVE an Advocate.
1 John 2:
APPLIES to Little Children “indicating” newer to BELIEVING, direction that to NOT commit Sin, is an upfront goal, but as you try and stumble along the way, you have an advocate Jesus the Christ....that you ARE already BELIEVING “IN”, IF he continues “BELIEVING IN”, and sins, he continues having an Advocate.
When a person IS BELIEVING, like a little child first learning something new, they stumble. We have example of Jesus’ own chosen disciples, grown men, first learning, stumbling, (even the most egregious stumble, of DENYING Jesus before other men) yet in his heart continuing to BELIEVE.
We obviously are to confess of our sins to Jesus Christ.
Not in question.
What is in question is ...... WHO is we, us, me, my.... and WHAT precisely does and does not APPLY to them.
Christianity is a Religion. The ASSUMPTION is every man professing to be a Christian ARE the exact same; We/ Us......
they aren’t.
Every person is an Individual. Every Individual being lead, choosing to step on the path through the narrow gate....while all are on the same path, they are on their own Individual Journey, to their end.
Scripture IMO, does a most excellent job of specifically addressing, Individuals in different stages of their Individual Journey.
While I believe God did place chapter and verses numbers later in the Bible, they technically were not there in the original writings. Sometimes a particular point or thought flows from one chapter into the next. This is one of those cases. Just reread 1 John 1:9 to 1 John 2:1 and it is clear that is all one continued thought or point. Granted, the whole letter or epistle has a connected overall theme or thought to the believers he was writing to. But John is not switching in changing topics between 1 John 1:9 and 1 John 2:1.
I am the ONE who is Qualified to speak what Scripturally applies to me, Since I am the ONE, who knows, what I read, what I study, what I believe, how long, what I do, what I do not do...
Already when through the little child stage, wondering, believing, hearing, reading, questioning, believing, Praying IN Jesus Name, tripping up, Repenting, Praying, Believing....
1) When I was (BELIEVING in) I was “with” the Lord, the Lord was “with” me .
2) Repeatedly the Lord was my Advocate, and repeatedly I could stumble, and repent.
3) And I “could have” continued that for the rest of my natural life.
4) I picked and chose how often, how much, how little, I heard, read, studied, spent time with the Lord.
5) And WHEN on the day I physically died, IS WHEN I WOULD HAVE BECOME SAVED.
6) On that ONE day I would Receive my Salvation, Nothing whatsoever would “undo” my salvation.
7) called born of God,
8) can sin, can appeal to my Advocate Jesus, can get back on track from my stumble, or can walk away, stay away, and not become saved.
Beyond BELIEVING, I chose to Give my Life unto Death (Crucified with Christ), Repent, CONFESS, to the Lord and receive His Once and forever Sin Forgiveness, His Once and Forever Salvation of my soul, His Once and Forever Quickening of my spirit, circumcision of my heart, etc. and Baptism of the Holy Spirit, His Spirit dwelling “IN” me, etc.
* NOW BEYOND BELIEVING (and hoping I endure to my end of physical life);
* The Lord IS “
WITH” me AND “
IN” me, Called CONVERTED IN Christ.
* I am free from Sin, can not Sin. Can not Fall away, am born of God, am begotten of God, am a son of God, am sanctified, am not subject to Wrath, am justified to be redeemed by the Lord, to meet Him in the air, and forever be WITH Him, etc.
* Saved ONCE, and forever.
* The Lords POWER IN me KEEPS ME WITH Him Forever.
* Nothing whatsoever can “undo” my Salvation.
Not every passage of Scripture applies to Unbelievers, to Jews, to Gentiles, to Believers, and not every passage that does apply to the Converted applies to Believers.
