I recently read a book called "Lessons I Learned in the Dark" by Jennifer Rothschild. She is blind, leads worship through playing piano by ear, and has two young sons. It's a great book! Here are my two favorite quotes from the book:
"Is your response to a difficult gift based on your feelings about the gift itself or on your desire to honor the Giver and do His will? Is your closed fist extended in anger or is your open hand lifted to Him? Only an open hand receives the blessings that accompany difficult gifts, and sometimes it's only in a package wrapped in heartache that we receive the fullness of God's grace."
"We often think that faith is a recipe for getting what we want from God. If that were true, it would mean that if I could muster enough faith, I would no longer be blind. But faith is not meant to offer an escape from life's difficulties; its purpose is to give us strength to endure them."
