Where does faith start?

I have always wondered where faith starts. Does it start when we hit rock bottom? Does it start when we are in complete darkness? Does it wait till we are on our last breath? Or does it start when we we feel empty and alone? In my experience, faith comes when we start healing our open wounds. When the light inside of you can’t be extinguished. When the heart does not shatter. Faith is always close. It can sense you.
