All Scripture….

2 Timothy 3:16-17(NKJV)

16All Scripture is given by inspiration of God, and is profitable for doctrine, for reproof, for correction, for instruction in righteousness, 

17that the man of God may be complete, thoroughly equipped for every good work.

Love Scripture like this.  Fist it tells us that ALL Scripture is given by inspiration of God.  To me that means that the Bible says exactly what God wants it to say. 

Does that mean everything in the Bible is 100% true?  I wouldn't go that far.  The Bible tells us that we are given the Holy Spirit to help us discern.  If everything was 100% true there would be nothing to discern.  I think God puts some stuff in there just to see if we are really paying attention.  

The above Scripture goes on to tell us what to use Scripture for.  For doctrine, for reproof, for correction (which is pretty much the same as reproof), and for instruction in righteousness. 

And what is the purpose of all this?  "That the man of God may be complete,...". 

If you want a manual for true success in life it is all there in Scripture!
