Scriptures alone are insufficient to guide the children of men to the presence of God

“We have the Bible, the Book of Mormon and the Book of Doctrine and Covenants; but all these books, without the living oracles and a constant stream of revelation from the Lord, would not lead any people into the Celestial Kingdom. … This may seem a strange declaration to make, but strange as it may sound, it is nevertheless true.

Of course, these records are all of infinite value. They cannot be too highly prized, nor can they be too closely studied. But in and of themselves, with all the light that they give, they are insufficient to guide the children of men and to lead them into the presence of God. To be thus led requires a living Priesthood and constant revelation from God to the people according to the circumstances in which they may be placed.” – George Q. Cannon (Gospel Truth, p. 252)
