I am a KJV only as well. Why? Because I once attended a church which used the NIV and everytime I tried to read that Bible, I felt a strong conviction. It just didn't carry the same "sense" of godliness to me that the KJV did. That was years before I learned anything about the translations - the Textus Receptus, etc. My husband knows all about that type of thing much better than I do. For myself, I can only say God showed me what He wished me to read long before I knew there was an issue with any of the newer versions.
I am saying this as to how I personally feel on the subject, not to be attacked on the subject. This is MY personal conviction. When I pick up the KJV and I start reading, I sense the Lord speaking to me. When I pick up other versions, I do not get that sense. So I read and trust ONLY the KJV.
And as to the losing salvation issue. Once upon a time I belonged to that group. I was "saved" several times and each time I backslid. But 4 years ago I was "truly saved". There was a difference. Each time I was "saved" it was mostly an emotional event and as such it was something that did not last. But 4 years ago I reached the end of myself, I truly acknowledged my failure to God, my overwhelming sin and I turned my life over to Him. THAT was when I was truly saved. This was a "commitment salvation", not an emotional salvation. Before, I just couldn't seem to remember to read my Bible, to pray, or anything I knew I should do. Now, when I don't read my Bible as I should, or I don't pray as I should, I sense something inside - the Holy Spirit - convicting me of it. That is the difference from when I was "saved" before. The Holy Spirit NOW lives in me, when before He did not. Forgive me if I'm not explaining it very well. Sometimes I am more articulate than others and right now I'm still in the middle of my first cup of coffee recovering from a migraine... So, now, I believe you can't lose TRUE salvation. But you can lose professed salvation if it's not real. Does this make any sense to anyone what I'm trying to say?
