I have not read all versions, but I prefer to have all versions.
Truth is not in the literal word! As 2 Corinthians 3:6 warns, the letter (literal) leads to death; only the spirit of scripture leads to life. This should be apparent in the difficult parables Jesus used. They were difficult for a reason. Those who clamor for easy are being lazy and God does not honor and respect laziness.
All versions have their flaws. Some leave out words. Some put in words. Some alter the original meaning. But none of them do this for all passages.
I've read KJV the most, but I see other versions of some passages that connect more deeply with me. Where KJV talks about charity, NIV talks about love.
The KJV version of 1 John 5:7 seems to talk about the Trinity, but the NIV leaves out this "trinity" wording. Why? The NCV has a footnote which explains that someone in the early church had added the extra wording, but does not explain why.
While researching for my most recent book, "The Bible's Hidden Wisdom: God's Reason for Noah's Flood," I used many versions, most available at http://BibleGateway.com. I also used the Lamsa version which supposedly has a more logical and understandable rendition of some otherwise confusing passages. And it seems to explain why the change was made -- because a misplaced dot in Aramaic or dot misread from a line above changed a word to the one ultimately used in most other versions.
There is a great deal of wisdom hidden in the Bible and some of it is lost with some translations, because the translator or scribe did not understand what they were writing. Or, in the case of the "trinity" passage, an overly eager scribe decided to add his own ideas. Oops!
Some people can think they are in the spirit and not be. I've done that numerous times. It's getting easier to spot it, but I'm far from perfect. When I'm in-spirit (Holy Spirit), the ideas flow, are full of love, and reveal wisdom that even I did not know when not in-spirit. It's humbling and sometimes a bit frustrating, but if we remain humble and hungry for God's answers, then we can find value in every interpretation of scripture, even those that may shock us or confuse us.
Each of us are looking at various versions of Truth, through our own filters. But there is only one Truth. The important thing is not to think that we have arrived, but to remain humble and hungry.
