In short, I will preach it [the Word], teach it, write it, but I will constrain no man by force, for faith must come freely without compulsion. Take myself as an example. I opposed indulgences and all the papists, but never with force. I simply taught, preached, and wrote God's Word; otherwise I did nothing. And while I slept, or drank Wittenberg beer with my friends Philip and Amsdorf, the Word so greatly weakened the papacy that no prince or emperor ever inflicted such losses upon it. I did nothing; the Word did everything.
Martin LutherIf there is anything in us, it is not our own; it is a gift of God. But if it is a gift of God, then it is entirely a debt one owes to love, that is, to the law of Christ. And if it is a debt owed to love, then I must serve others with it, not myself.
Martin Luther
