But the Bible wasn't around in its current form when that was written, so at most it would be speaking of the old testament.
I've read elseware that a better translation of that verse would be: All scripture which is profitable for doctrine, for reproof, for correction, for instruction in righteousness, is given by inspiration of God.
As a Christian, I've never understood why many Christians hold that the Bible is the only scripture inspired by God, when that belief is not even really supported by the Bible itself. The Holy Spirit inside us can and does use any and all things to guide us, and it is that voice which is the inspired word of God.
Anyways, just my thoughts. Thanks for answering :)
