Do you believe the KJV itself is inspired? I like and prefer the KJV but do not view it as a final authority. I also prefer the TR over Nestle or the Majority.
I hold to two different possibilities on what inspiration means in the Scriptures.
Possibility #1. - Only the originals were inspired and that inspiration is carried through preservation (Note: This is the standard KJV-only belief and it is also held by some TR-only believers). So under this view, the KJV is not a re-inspiration (i.e., it is not a double inspiration), but the KJV is merely evidence of the preservation of God's words from the inspired originals.
Possibility #2. - The word "inspiration" simply means "illumination," that is, God giving a person understanding. Job 32:8 says, "But there is a spirit in man: and the inspiration of the Almighty giveth them understanding." This suggests that inspiration can involve God enlightening the mind. In that sense, when 2 Timothy 3:16 says, "All Scripture is given by inspiration of God," it could mean that God illuminated the minds of the writers, enabling them to understand and faithfully record the truths He wanted revealed. If that is the case, I see the KJV translators and the later KJV edition scholars as being illuminated, or inspired at select points in time, to understand what God really was saying to convey the meaning of the text, which I believe is settled with the Pure Cambridge KJV edition (circa 1900).
Side Note:
I am glad you are at least TR. That is a way better position than both the Majority Text and Critical Text positions where they constantly are updating the text. The Beza 1598 Greek (available to read free at Archive.org) is 99.98% the Greek that underlies the KJV. There are only about 20 or so translatable differences between the KJV and Beza's 1598 Greek. Nick Sayer's, who interviewed me is more for the TR and he is not against doing updates for the KJV (Even though I disagree with that position). Nick came out with his own New Testament KJV update. I agree with some of his changes but not others in his KJV editions.
Anyways, today, people can use ChatGPT to help explain the Greek in the Beza 1598. But the problem is that it may sometimes favor the Critical text definitions that are found in Modern bibles that runs contrary to the KJV reading. Granted, it is better to learn Greek for oneself, but we do all have lives and or other callings from the LORD, too.
In any event, I hope you get a chance to check out my PDF when it is finished next week (Lord willing).
