Faith is a living, bold trust in God's grace, so certain of God's favour 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 LutherHe that will maintain that man's free will is able to do or work anything in spiritual cases, be they never so small, denies Christ.
Martin LutherIt is certainly true that reason is the most important and the highest rank among all things and, in comparison with other things of this life, the best and something divine. It is the inventor and mentor of all the arts, medicines, laws, and of whatever wisdom, power, virtue, and glory men possess in this life.
Martin Luther
