You know, when I was released from prison, I was attending a small church in my hometown. The Pastor there used the NIV. Now remember that the NIV was still relatively a new thing at this time.
He preached a sermon once on one verse from the NIV which though I didn't know it at the time, was totally wrong!
He based his whole message on 1 Cor. 7:1.
The original NIV as released in 1978 said: "Now, to the things you wrote me about, it is good for a man not to marry."
Now he preached a whole sermon telling people that they should not marry. And I totally disagreed with that.
The editors of the NIV have since changed the reading, but in its original issue, that is what it said because I know, I was given the NIV by a young lady at church as a gift.
I was raised on the KJV. It is the version I study, teach, and preach from. However, I do not limit myself to it alone. I also consult other versions, and always read what the Greek says.
I will say this however, with the exception of the NWT, of all the disputed texts from the Greek to our Bibles, no doctrine on which Christianity stands upon, hinges on these disputed texts.
If the NIV is the version you study, read, etc., then I say God Bless You.
I like the KJV, but I also rely heavily on the Greek text of the NT.
God Bless
Till all are one.
