I do think folks grow in Christ.
That being said, however, makes me think you don't think "being in Christ" is enough to keep one free from sin.
You keep falling back on the "as I mature I will see things as sin that I don't already know are sin".
That is a mistake.
Ephesians 4:15
but speaking the truth in love, we are to grow up in all aspects into Him who is the head, even Christ,
Hebrews 6:1-2
Therefore leaving the elementary teaching about the Christ, let us press on to maturity, not laying again a foundation of repentance from dead works and of faith toward God, of instruction about washings and laying on of hands, and the resurrection of the dead and eternal judgment.
James 1:2-4
Consider it all joy, my brethren, when you encounter various trials, knowing that the testing of your faith produces endurance. And let endurance have its perfect result, so that you may be perfect and complete, lacking in nothing.
Romans 5:3-4
And not only this, but we also exult in our tribulations, knowing that tribulation brings about perseverance; and perseverance, proven character; and proven character, hope;
2Peter3:8
but grow in the grace and knowledge of our Lord and Savior Jesus Christ To Him be the glory, both now and to the day of eternity. Amen.
OK Let's also look at what Paul said.
Philippians 3:12
Not as though I had
already attained,
either were already perfect: but I follow after, if that I may apprehend that for which also I am apprehended of Christ Jesus.
13 Brethren, I
count not myself to have apprehended: but
this one thing
I do, forgetting those things which are behind, and reaching forth unto those things which are before,
14
I press toward the mark for the prize of the high calling of God in Christ Jesus.
So we see here Paul even said He was not perfect or perfected.
He has the same Holy Spirit that we all do.
Paul said he moves forward towards Christ.
That's Growing in your knowledge and understanding in Christ. Maturity in Christ.
1corinthians13:9
For we know in part, and we prophesy in part.
Now our knowledge is partial and incomplete, and even the gift of prophecy reveals only part of the whole picture!
So if WE ONLY KNOW IN PART then there are things we don't get know. Those things we don't get know are as holes in our doctrine or MISSING UNDERSTANDING - KNOWLEDGE.
As we grow we become more like Christ Jesus and this means we become into a more Holy State and More Righteous State.
So if we become more like Christ then that light will SHOW UP THINGS ABOUT YOU that need to change - other wise you won't be able to walk in this new light.
Those things exposed by this new light in you will now become sin in you. Anything the Light exposes that needs to be changed - if left unchanged becomes disobedience which is also sin.
Do you think you have So much Christ in you that you have nothing to change?
Please stop tearing down brothers who are striving to grow in Christ and become more and more perfected in Christ - that is not pulling them out of fire.
Blessings to you
