We 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 LutherO, this faith is a living, busy, active, powerful thing! It is impossible that it should not be ceaselessly doing that which is good. It does not even ask whether good works should be done; but before the question can be asked, it has done them, and it is constantly engaged in doing them. But he who does not do such works, is a man without faith. He gropes and casts about him to find faith and good works, not knowing what either of them is, and yet prattles and idly multiplies words about faith and good works.
Martin LutherThe slender capacity of man's heart cannot comprehend the unfathomable depth and burning zeal of God's love toward us.
Martin LutherA Christian is free and independent in every respect, a bond servant to none. A Christian is a dutiful servant in every respect, owing a duty to everyone.
Martin Luther
