The NKJV showed up on the scene in 1979, as a re-interpretation of the KJV by a group of people comprised predominantly of Baptists, and a few conservative Presbyterians. Comparing the NKJV with other versions shows that they've changed and added words which significantly change the meaning of passages, so that they don't quite agree with any other version of the Bible out there. There's no evidence to show (even from a religious standpoint) to suggest that this committee of men was any more divinely inspired by God than any other group of translators that came before them, and, given their religious affiliations, I'd suggest it likely that they produced a version in line with their collective interpretation. Once again, whose translation is correct? I'd be willing to bet that I could pick nearly any other version at random, and it wouldn't be nearly so explicit.
