What a silly question - how does this in any way pertain to the KJV being inspired of God and all the other translations being wrong?
The NIV says this:
30 And if your right hand causes you to stumble, cut it off and throw it away. It is better for you to lose one part of your body than for your whole body to go into hell. Matt 5:30 NIV
The same grisly advice!
So, the KJV and the NIV can be interpreted in exactly the same way.
In what way is the KJV superior, inspired of God etc, and the NIV not, according to this verse?
