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 LutherIn ourselves, we are sinners, and yet through faith we are righteous by the imputation of God. For we trust him who promises to deliver us, and in the meantime struggle so that sin may not overwhelm us, but that we may stand up to it until he finally take it away from us.
Martin LutherNot 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 Luther
