Learning to live by faith and not by sight

Is it about falling? Or the mistakes we make? Or is it really about whether we climb when we fall, and our reactions to the life around us? Sometimes I hold my breathe and tiptoe around because I'm scared of falling. I don't want to have the wrong reaction so I have no reaction.  But that doesn't keep life from happening, and I still fall. I'm learning I can't keep everything in perfect balance. I'm learning its about trusting and not controlling. I hear God asking me to let go.  He knows I'm going to fall, He's knows how to help me climb, so what am I so afraid of?
