“Search These Commandments”
Doctrine and Covenants 1:37
37 Search these commandments, for they are true and faithful, and the prophecies and promises which are in them shall all be fulfilled.
The Prophet Joseph Smith said:
“Search the scriptures—search the revelations which we publish, and ask your Heavenly Father, in the name of His Son Jesus Christ, to manifest the truth unto you, and if you do it with an eye single to His glory nothing doubting, He will answer you by the power of His Holy Spirit. You will then know for yourselves and not for another. You will not then be dependent on man for the knowledge of God; nor will there be any room for speculation.”
(In History of the Church, 1:282.)
