“ I challenged God. I said, 'God, I know that I'm a sinner. I know that I won't probably have peace until You're in my heart. But I will not let You in my heart until You answer me, why? Why did you take my arms and legs? Why didn't You give me what everybody else has? God, until You answer me that question, I will not serve You.' ”
