David B. Haight
The Latter-day Saints have learned the truth that the everlasting gospel has been restored. And what does this knowledge bring to them? It brings to all who have honestly and sincerely obeyed the principles of repentance and baptism the gift of the Holy Ghost, which enlightens their minds, quickens their understanding, and imparts unto them a knowledge of Christ.
The Latter-day Saints have a guide, a help, a means to assist in their acquisition of truth, in their desire to know what their duty is, that the world does not possess. And this guide is necessary; man cannot find out truth-he cannot find out God by intellect alone. It has been said that no man can find out God by a microscope. Reason alone is not a sufficient guide in searching for truth. There is another, higher, more sure guide than reason.
That guide
is faith-that principle which draws our spirit into communion with the
higher Spirit which will bring all things to our remembrance, show us
things to come, and teach us all things. To acquire that Spirit is the
responsibility of the Latter-day Saint who would know truth. (Gospel
Ideals, p.139)
