From the 2013 New World Translation 2 Tim. 3:16 -
All Scripture is inspired of God and beneficial for teaching, for reproving, for setting things straight, for disciplining in righteousness, so that the man of God may be fully competent, completely equipped for every good work.
As JW's we must have read that scripture a thousand times. Oh, we understood it alright. But it went in one ear and right out the other. The bible says that it can make a person fully competent, fully equipped, lacking nothing. The KJV says it will make a person "perfect" meaning whole, or lacking nothing at all.
How many times did we read this scripture and then turn right around and continue reading a WT bible study aid? Why did we feel compelled to study a bible study AID when the bible is what will make a person complete?
Why did we feel compelled to give over our eternal destiny to a publishing company; who hijacked the term "Truth", in place of God's Word, and presented themselves as what is needed in order for a person to be complete.
The simple and embarrassing reason is that even though we understood 2 Timothy 3: 16, we didn't believe it.
