Where faith is not continually kept in motion and exercised, it weakens and decreases, so that it must indeed vanish; and yet we do not see nor feel this weakness ourselves, except in times of need and temptation, when unbelief rages too strongly; and yet for that very reason faith must have temptations in which it may battle and grow.
Martin LutherLet every man recognize what he is, and be certain that we are all equally priests, that is, we have the same power in the word and in any sacrament whatever.
Martin LutherAnd though this world with devils filled, Should threaten to undo us, We will not fear, for God hath willed His truth to triumph through us.
Martin Luther
