Here in verse 7 Joseph Smith gives us a nice recipe for what to do to build up our faith. 1st, we become diligent seekers 2nd, We make sure that as we seek we are doing so out of the best books. And 3rd, we bring all the faith we can muster to our studies. We should always study in a way that is seeking to confirm faith.
