Is There a Problem With Applying What I Know?

I think that we have this overall arching belief of god, but sometimes our belief in who he is wavers. And so i think my application begins to waver when i just start to believe that maybe, you know, god isn't going to show up. In those times and losin faith, we have a hard time of plying what we know because we simply don't remember the god of the past. So there is a kind of faith that doesn't actually change behavior. It's only an a, an acknowledgment of a truth, right?
