I have often said that diagramming Ether 3:19 last phrase, "...and he had faith no longer, for he knew, nothing doubting" would put faith and doubt on the same side of the equation.

I’ve been told that you can’t actually show courage unless you’re afraid. Faith is like that too. We can’t actually demonstrate faith unless we’re facing uncertainty. As Elder John A. McCune described, “There will be times when we will not be able to see any way that a current situation will end well…” (1) Like when you’re standing on the shores of the Red Sea while Pharaoh’s army races toward you in their chariots. When you have absolutely no place to go. That is where faith lives.
