I did nothing; the Word did everything

I ran across this quote from Martin Luther which I thought to be a particularly strong contrast to the attempts people make in this day and age to try and accomplish the work of God using the power of man:

In short, I will preach it, 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
