What's amazing is the KJV spurred on the greatest revival the world has ever seen. That's called fruit. The new versions have led to the Laodicean Age. That's called corrupt fruit.
So, you mean a revival hundreds of years later? Literally? I assume you are talking about the Great Awakening. And of course, God's word does not return void! After a few hundred years, of people reading in a language that was much closer to their own, the HOLY SPIRIT started an Awakening!
Because a Bible version does not start an Awakening! God does! Of course, he used the only Bible that was available. And no one is denying the gospel is there in the KJV. The additions and corruptions do not touch on the central truth of who Jesus is! In any version that is not cultic, the message is clear. As I said in another post, 1 Cor. 15 is clear in any version, and it is also a portion of Scripture that basically has only a few variations in the manuscripts. Get an UBS Greek New Testament and it will tell you every variation, including in the Byzantine texts. So much for text perfection!
In fact, as someone who tried to read the KJV as a child of 11, even memorizing Psalm 8, I was so taken from its beauty, I finally gave up, because I did not understand the language. What if I had had access to a modern version? I might have saved myself a lot of trouble wandering in the wilderness for 15 years, doing harm to myself, if I had a modern version in my own language.
I would suggest that, in fact, the KJV is what has lead to people walking away from God. Because, it may have taken a few months, but reading in a modern version was something that led to me finally understanding the gospel message. But only with the help of God!
The other essential part of revival, and people being saved, which you fail to acknowledge is prayer, and the fervent witness of many people. I knew people that God saved in miraculous ways, and they were on fire for God. There WAS a revival where I lived. The more they witnessed to me, the more I knew something was up. And yes, God saved me, through the Word, but also through the prayers of God's people and their testimony.
What is missing today is a fervent witness and honest prayer! Fortunately, there are now bible translations that anyone can understand, from phrase for phrase, like the Message, or the NLT, to word for word, like the ESV and NASB, and a few Bibles in between, like the NIV, HCSB and NET.
I can agree totally that the KJV was mightily used of God, back in its day. And for some people, it is the translation they are comfortable with! But, God has led modern scholars to translate the Bible into the language that people speak today, not a translation in early modern English. Or, for that matter, God has led translators in literally hundreds of languages, to make the Bible available to all!
