My dh and I have sometimes received odd looks when we tell people that we only read the KJV bible - one bible is like all, right? Thankfully, we were mentored and ministered to by Faith Baptist Church and Pastor Robert Monteith in Misawa, Japan. He has since moved to another church, but his ministry will always remain in our hearts and we are forever thankful to have received sound doctrine and bible-based preaching from our first church. We can clearly see the difference between his ministry and the worldly Christians that are rampant in the US... I can only imagine what we would be teaching our children if we had never met Pastor Monteith (we wouldn't be homeschooling, that's for sure).
Here is a list of the verses that are COMPLETELY GONE from the NIV Bible...
Mark 16:9-20 (all 12 verses)
I John 5:7
Now, I don't know about you, but I certainly don't have enough confidence to tell God that these verses don't belong in the bible (some about salvation through Christ, one about the Holy Trinity...) so I'll be reading the KJV. If you read an NIV, maybe you should take a look at these verses to see if they're important to you.
