MARTIN LUTHER
“Faith is God’s work in us, that changes us and gives new birth from God (John 1:13). It kills the Old Adam and makes us completely different people. It changes our hearts, our spirits, our thoughts and all our powers. It brings the Holy Spirit with it. Yes, it is a living, creative, active and powerful thing, this faith. Faith cannot help doing good works constantly. It doesn’t stop to ask if good works ought to be done, but before anyone asks, it already has done them and continues to do them without ceasing…
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”
(from “An Introduction to St. Paul’s Letter to the Romans,” Luther’s German Bible of 1522, Translated by Rev. Robert E. Smith)
