“In short, I will preach it [the Word of God], 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.  Had I desired to foment trouble, I could have brought great bloodshed upon Germany; indeed, I could have started such a game that even the emperor would not have been safe.  But what would it have been?  Mere fool’s play.  I did nothing; I let the Word do its work.”

Martin Luther, quoted in Michael Horton, the Gospel-Driven Life, 199.
