Take 40 days to overcome your fears.
Amazon review: Each day of this devotional is fantastic. I found that within a few days I was learning to focus more on God than on fear and anxiety, anxiety that I wasn't even aware I was holding onto. The author encourages you to take 40 days to complete the study, one day per each devotion. But I have found that I like to ponder each new lesson for a few days before I move on. Each lesson focuses on an aspect of God and includes a scripture to support it, an examination of it, a prayer, and an evening look back to see how you did. I typically do that at the beginning of the next day.
