One of the fundamental components of true faith is a correct understanding of the attributes of God. This includes a correct understanding of His perfected, tangible body and the perfection of his omnipotence, omniscience, etc.
Joseph Smith
"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." (Lectures on Faith, p. 33)
