He understands mine just fine,
Good job ,if you can't win change the subject.
Obviously, if you still read the KJV, you must believe there is an acceptable trade off between accuracy and intelligibility (ie it is reasonable to forgo reading in the original texts, ensuring accuracy, in order to make it easier to read the Bible in your own language) but you haven't justified why your balance is more acceptable than other people's, except to say they should read the KJV because it's older/more difficult to read. Hence my argument. Have a think about why you read an English translation at all, and then think about why people today might prefer the English of contemporary translations compared to the English of the 1600s.
So why don't you read those instead of an idiots version. Whats the point. If you can read Hebrew then why argue and greek, my goodness you of all people should Know how the NIV has butchered the bible. It is the new idiots version.
If you need the NIV then God bless you and I hope you find peace and happiness.
... And I hope that means you have changed your mind about the mental abilities of people who think use of the NIV is acceptable. But it is possible to not be an idiot and endorse use of the NIV, and it is possible to be 'concerned with your walk with God' and endorse its use, as well.
