"and you will know the truth, and the truth will set you free.” John 8:32 ESV
"Thomas said to him, “Lord, we do not know where you are going. How can we know the way?”6 Jesus said to him, “I am the way, and the truth, and the life. No one comes to the Father except through me." John 14:5-6 ESV
First, you have completely lost your credibility, by quoting John 8:32 without the reference, and in your context, you seem to be implying that the KJV is the "truth" instead of Jesus Christ, as he says only 6 chapters later. Jesus is the "truth." Not the KJV.
Second, there is a search function on the top right corner, if you want to read the threads in which people claim the KJV is the only proper translation, "authorized" by God - ie, King James, then you might want to do a search and spend a few days reading. You will get to know all the people who unsuccessfully tried to convince this forum that they were right about KJV Only, and those of us with training in reading Biblical languages were wrong about all the additions, mistakes which I in particular hammered home on many occasions. (Or read this thread - certainly many have posted on it - including me!)
Third, spend some time in this forum, before you ask these silly rhetorical questions in which we know the answers, but you pretend you don't. I have refuted the myth of the KJV being the only Bible on multiple occasions. Thank you!
As for the KJV, it is beyond my comprehension - all those archaic words and grammatical uses especially second person singular. Maybe if there were courses on Elizabethan grammar, I might feel differently, but until that day, the KJV is strange and alien to modern English. Then there are the mistakes which abound.
BUT- it has a wonderful history, and I think we should all be grateful, that at the time, it was a Bible in English for the common people. However, today, we need to use today's language to communicate, and certainly we have come so far in Bible scholarship with manuscripts that were not found until recently, especially the much earlier manuscripts than the 7 corrupt manuscripts that Erasmus, the Catholic priest used, which was then used by the KJV translation committee. (Yep the KJV is a Catholic Bible!)
So if the KJV works for you, I think that is wonderful. Continue to read it to grow closer to God. But no, you are never going to convince someone who loves reading Greek as much as me, with a Greek professor on the ESV and NIV translation committees that the KJV is the only right translation. The KJV is no longer communicates effectively, (and is ridden with small errors, although they don't change much doctrine,) and certainly for the average westerner, is not the best choice for devotions or study. Or preaching or teaching!
