I have a positive conviction that God is a reality—that he lives. He is our Heavenly Father, and we are his spiritual children. He created the heaven and the earth and all things upon the earth and is the author of the eternal laws by which the universe is governed. These laws are discovered bit by bit as man continues his search, but they have existed always and will remain unchanged forever.
President Howard W. Hunter, "To Know God", General Conference, October 1974
I find myself dwelling or pondering on many unknowns in the gospel and the reason of our existence. But, is that always wise to think about those? It is definitely good to be inquisitive. Definitely good to want to expand our limited knowledge. But I need to be careful, we all need to be careful. Take caution so as not to be seduced by speculation. Take caution so as not to be enticed by our limited, extremely limited, knowledge of things as they actually are, as God sees them and not as we perceive them.
There are things we simply don't understand. There are things we cannot fathom. There are things that we want to justify in our own logic so that we appease somebody else's logic, or negate somebody else's logic, as is the case many times.
Mortality is difficult. It is strange. It is weird. Some things in life are changeable. And some things in life are not, no matter how much we want to change them. They are eternal. We can either lean on the very limited wisdom of man and woman to help us navigate this life. Or we can have God lead us. It is a very good thing we have a Father, who knows everything, who is all wise, and will not deceive or lead us astray. But He will not force us down His path. He is giving, and has given, us tools to guide us. All we have to do is use them, and use them unhipocritically, meaning because we really want to know the "way, the truth, and the light". Not just appear that we want to know.
