I would just like to point out that when King James had the KJV version of the bible written, he changed a lot of words to fit what he believed rather then what it actually said
baptidzo---english translation---submersed
this is the word used every time that baptism is mentioned, before KJV, it was never called baptism, but because King James didnt believe in submersion, he changed the word.
also the newer translations, including the NIV, ASV, NASV and many others, are based on much older documents then the KJV, are better translated in many cases, and are based on many more writeings.
in the end, KJV is a great bible, but no better or worse then the NIV
