To name an example, words like grace are so present in this NIV Bible, and I think the replacement in the NWT of grace for 'undeserved kindness' really is a shame. It does not read the same, and to me it feels like the meaning also changes somehow.
@Yesu Kristo Bwana Wangu, I agree, and I debated this with a JW yesterday online. He insisted that "undeserved kindness" is the same thing and that we DON'T deserve it. It seems pathological that he would prefer this, but he probably doesn't see it that way.
