When 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 LutherNow the Church is not wood and stone, but the company of believing people; one must hold to them, and see how they believe, live and teach.
Martin LutherWe conclude, therefore, that a Christian lives not in himself, but in Christ and in his neighbor. Otherwise he is not a Christian. He lives in Christ through faith, in his neighbor through love. By faith he is caught up beyond himself into God. By love he descends beneath himself into his neighbor.
Martin LutherAs long as a man is persuaded that he can make even the smallest contribution to his salvation, he remains self-confident and does not utterly despair of himself, and so is not humbled before God. Such a man plans out for himself a position, an occasion, a work, which shall bring him final salvation, but which will not.
