We find ourselves, therefore, much like the Nephites when Nephi spoke of revelation: ‘And now I, Nephi, cannot say more; the Spirit stoppeth mine utterance, and I am left to mourn because of the unbelief, and the wickedness, and the ignorance, and the stiffneckedness of men; for they will not search knowledge, nor understand great knowledge, when it is given unto them in plainness, even as plain as word can be.’
We have little occasion to clamor for more revelation when we refuse to heed what the Lord has revealed for our salvation. However, the authorities are directed by revelation, and this is apparent to all who have the spirit of discernment. The Lord has not forsaken his people, although they have not always put their trust in him.
(Joseph Fielding Smith, Doctrines of Salvation, 1:283)
