With so many modern translations, it is hard to pick one over the other. Some have even partied into groups, especially of note currently are "KJV onlies" and "anti-KJVs". Hmph. Now we start getting into dangerous ground! Here's the deal for me, personally. I have used an NIV since I was born again. Had 2 sitting around the house, and was given another study-version later. God blatantly saved my soul by His good graces - completely undeservingly (oh if you only knew) - and He did so knowing that all I had sitting around and all I would be studying out of for some time was an NIV.
God used it in conjunction with many other things, people, and His Spirit, to lead me into great understandings which I would be wrong to not share with others, as has been shared with me, and which certainly coincide with other translations. Unfortunately, many of the notes here quote scripture from the NIV, and the copyright alone makes it difficult to share with others directly.
Here's what mine says:
"The NIV text may be quoted and/or reprinted up to and inclusive of one thousand verses without express written permission of the publisher, providing the verses quoted do not amount to a complete book of the Bible nor do the verses quoted account for 50% of the total work in which they are quoted."
(various emphasises (sp?) mine)
Sure is fishy, copyrighting God's Word and all (granted they claim it is a thought for thought translation versus a word for word translation). Yes there are arguments that the publisher of this translation also publishes the Satanic Bible, amongst other questionable things. Which one can then say that by buying an NIV, you supports the teaching of the Satanic Bible, etc. You know that there are many arguments against the KJV as well?
The arguments on both sides are well-founded, and I continue to use my NIV at times, though I really prefer what's in the KJV because sometimes the NIV seems to lose something quite beneficial in its striving for "ease of understanding".
Anyway, I don't fear (at least I don't think that's it… and may please God show me otherwise if I have hidden it from myself!) standing my ground and saying one or the other is just plain wrong… I'm just not convinced that this is true. But certainly due to the copyright issues, it will be impossible to legally quote the NIV very much, so it disqualifies itself in this case.
Most places on this site will likely use the KJV simply because that's the Bible I already use, and even with all the criticism there's not a whole lot wrong with it, and occasionally other texts in the public domain will be quoted when they help in understanding.
That's all I have to say on the subject without some further conviction from God. Whichever translation of God's Word you use, go for it! He will give you conviction if a change needs to be made. Just be willing to listen. If you see a problem in your translation… investigate with an open heart, and let God lead you to the truth. That's all :)
It makes no difference which translation anyone of us uses if the Spirit of God isn't present to open scripture up to us - so not-a-one-of-us may boast. May God's grace be with us as we study His Word, and His Will be done in spite of ourselves. Amen.
