When some say that good works are forbidden when we preach faith alone, it is as if I said to a sick man: "If you had health, you would have the use of all your limbs; but without health, the works of all your limbs are nothing"; and he wanted to infer that I had forbidden the works of all his limbs.
Martin LutherWhen my heart is cold and I cannot pray as I should I scourge myself with the thought of the impiety and ingratitude of my enemies, the Pope and his accomplices and vermin, and Zwingli, so that my heart swells with the righteous indignation and hatred and I can say with warmth and vehemence: 'Holy be Thy Name, Thy Kingdom come, Thy Will be done!' And the hotter I grow the more ardent do my prayers become.
Martin Luther
