Whenever the true message of the cross is abolished, the anger of hypocrites and heretics eases and all things seem to be at peace.
Martin LutherWe can mention only one point (which experience confirms), namely, that next to the Word of God, music deserves the highest praise. No greater commendation than this can be found — at least not by us. After all, the gift of language combined with the gift of song was only given to man to let him know that he should praise God with both word and music, namely, by proclaiming [the Word of God] through music.
Martin LutherNight and day I pondered until I saw the connection between the justice of God and the statement that 'the just shall live by his faith.' Then I grasped that the justice of God is that righteousness by which through grace and sheer mercy God justifies us through faith. Thereupon I felt myself to be reborn and to have gone through open doors into paradise.
Martin LutherWhere 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.
