"Let us here observe, that three things are necessary, in order that any rational and intelligent being may exercise faith in God unto life and salvation.
"First, The idea that he actually exists.
"Secondly, A correct idea of his character, perfections and attributes.
"Thirdly, An actual knowledge that the course of life which he is pursuing, is according to his will. For without an acquaintance with these three important facts, the faith of every rational being must be imperfect and unproductive; but with this understanding, it can become perfect and fruitful, abounding in righteousness unto the praise and glory of God the Father, and the Lord Jesus Christ." (Joseph Smith, Lectures on Faith, Third Lecture. Emphasis in original)
