The actual King James Version of this is as follows:
All scripture is given by inspiration of God, and is profitable for doctrine, for reproof, for correction, for instruction in righteousness:
Now I must say as I was preparing for this by looking into the original Greek that all humans make errors. In a previous post I had stated that This letter was not “scripture” at the time it was written (You can’t cherry pick God), but as you look the meaning of the Greek you come to realize that anything that meets the criteria set forth in this verse can be considered “scripture” for it is given unto the writer through the Holy Spirit. So I admit I was wrong and will do better in the future.
What is truly important beyond that fact that is given to any through the Holy Spirit is these criteria items:
It is for doctrine which actually means for instruction meaning to give those that have read it the ability to teach it unto others.
It is for reproof or evidence you can use to show someone they have not been following the teaching of God. I wish to stick on this one for a moment. Several times I have done this very thing. Used this book the Bible as a foundation to show that someone has erred in their ways and choices. They have allowed themselves to fall into a misguided lifestyle thinking they are one with God but the Bible itself says otherwise. So I challenge them I show them the proof and the say I am judging them. I tell them it is not me judging them but the word of God. Yet still I am the scapegoat that has judged them and they turn from me vindicated that they are in the right when it is not me that is right and especially not them, but the Bible is right and correct and proof that they are in the wrong and not following the teaching of Christ or His Father.
This leads right into the next word “correction” meaning to fix your ways to match that of the Bible it is here that many fail to do so especially those that have labeled the person actually trying to help them as a “judge.”
For truly what is the Bible? It is an instruction manual in righteousness designed to embed character into us through moral facts presented within the Bible.
As I have said more than once if it is called a sin in the Bible then it is a sin and you need to work on trying to stop it.
