I was thinking about it last night and I realized that I didn't grow up with the KJV at all. I just assumed I did but then I realized:
When we were saved, my mom was using the Living Bible.
Then I went to a Christian school under the Dutch Reformed Church so we used the RSV.
Oh wait - I DID use it for a couple of years when I went to an American Baptist Church in the late 70s, so I did use it for a little while.
Then I went to the Presbyterian Church who used the 84NIV and I used that for many years.
Somewhere in there I picked up the NASB for study - I think it was when I was still in the ABC.
When the ESV came out, I did some looking into it and liked it so I got one but didn't fully use it for a year or so and then I switched. I still have my NASB and 84NIV though.
So, I was saved, my entire family was saved (18 members of my extended family were saved within 6 months of my mom being saved) - all out of the Living Bible!! Other than those few years, I didn't use the KJV. Don't get me wrong - it's a great version but in my life, it was not the Bible that my churches used other than the couple of years in the ABC.
But yes, I do say that God has used the NIV greatly - as He has the KJV, ESV, NASB and even the Living Bible.
