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? Is the station and high achievements of some individuals a proper yard stick? By what measure is the validity and reliability of their work and words measured? Can one feel safe and secure in the established order of what has been generally accepted by the great majority? Truly the last question one should ask is: was God so nieve 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?
