I have been here before, but years ago. (I forget my old username).
I grew up with KJV/NIV translations; knowing within myself that what I was reading wasn't right (because there was no pattern of sound words). I had the Witness in me at this time, but no good head-knowledge. (The head knowledge came later (when I discovered Gary Amirault (around 2006))). (Gary was essential in my learning).
Before that; God Himself had done various: 'wonders' to show/teach me... He did not leave me as an orphan.
As the years have passed I have ALWAYS found that PROPERLY translated Scripture bears witness to my inner witness.
