“Faith is a living, bold trust in God's grace, so certain of God's favor that it would  risk death a thousand times trusting in it. Such confidence and knowledge of God's  grace makes you happy, joyful and bold in your relationship to God and all  creatures. The Holy Spirit makes this happen through faith. Because of it, you  freely, willingly and joyfully do good to everyone, serve everyone, suffer all kinds  of things, love and praise the God who has shown you such grace.”
~ Martin Luther
