Priesthood Through the Scriptures

How does one obtain the wisdom to discern between the truth and that which is false? Can one look to the institutions of higher learning?

Truly, the last question one should ask is, Was God so naive as to leave mankind without the means to find out the truth in such a way as to preclude any chance of missing the mark?
