"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." Joseph Smith, Prophet

Alma 32:21

And now as I said concerning faith — faith is not to have a perfect knowledge of things; therefore if ye have faith ye hope for things which are not seen, which are true.
