Let your faith be greater than your fears.
I have a little "teacup" Maltese that was already an adult when we got her. Maddie wasn't socialized until she came to live with us and when we have company, she wants me to hold her. It's taken years for her to allow strangers to come close to her and that's only when I'm holding her. She trusts that I will protect her and keep her safe so, even though she's afraid, she has courage when she's in my arms.
I feel the same way about God when I'm facing something scary. I trust that he will keep me safe and that gives me the courage to "step out in faith".
