Not only the adoration of images is idolatry, but also trust in one's own righteousness, works and merits, and putting confidence in riches and power. As the latter is the commonest, so it also is the most noxious.
Martin LutherRest in the Lord; wait patiently for Him. In Hebrew, "Be silent in God, and let Him mould thee." Keep still, and He will mould thee to the right shape.
Martin LutherIn 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.
