Joseph Smith’s “Lectures on Faith: Lecture #3:12-19 “From the foregoing testimonies, we learn the following things respecting the character of God. First, that he was God before the world was created, and the same God that he was, after it was created. Secondly, that he is merciful, and gracious, slow to anger, abundant in goodness, and that he was so from everlasting, and will be to everlasting. Thirdly, that he changes not, neither is there variableness with him; but that he is the same from everlasting to everlasting, being the same yesterday today and forever; and that his course is one eternal round, without variation. Fourthly, that he is a God of truth and cannot lie. Fifthly, that he is no respecter of persons; but in every nation he that fears God and works righteousness is accepted of him. Sixthly, that he is love.
An acquaintance with these attributes in the divine character, is essentially necessary, in order that the faith of any rational being can center in him for life and salvation. For if he did not, in the first instance, believe him to be God, that is, the creator and upholder of all things, he could not center his faith in him for life and salvation, for fear there should be a greater than he, who would thwart all his plans, and he, like the gods of the heathen, would be unable to fulfill his promises; but seeing he is God over all, from everlasting to everlasting, the creator and upholder of all things, no such fear can exist in the minds of those who put their trust in him, so that in this respect their faith can be without wavering.”
